TL;DR: We ran OpenClaw in production for 10+ days across multiple agents and model providers. The documentation covers setup. It does not cover what breaks after you deploy. Here are 7 silent failures we discovered: config drift across four separate model stores, heartbeats that die without logging errors, a gateway race condition that overwrites your edits, agents rewriting their own configs, upgrade-induced config drift that breaks three systems at once, hidden cost traps, and hot reload behavior that silently fails. Each gotcha includes the symptom, root cause, and fix.

OpenClaw production is where the real learning starts. The setup guides will get you running. They won’t tell you what breaks at 2 AM on a Tuesday when your cron jobs silently switch back to a paid model you thought you disabled three days ago.
We’ve been running OpenClaw as a self-hosted Docker deployment for over 10 days with multiple agents, multiple model providers, and three platform upgrades. This post is the guide we wish existed when we deployed. Every gotcha here comes from actual debugging sessions and hours we lost to OpenClaw silent failures that produce no error messages and no log entries.
If you haven’t set up OpenClaw yet, start with our OpenClaw setup guide . This post assumes you’re already deployed and wondering why things aren’t working the way the docs say they should.
The Four Model Stores: Why Config Changes Don’t Propagate

What you see: You change the model in the main config file. Interactive sessions use the new model. But cron jobs keep using the old one. API costs spike from an unintended fallback.
Why it happens: OpenClaw stores model configuration in four separate places:
- Main config file (defaults and per-agent model settings)
- Session state files (cron sessions bake the model at creation time)
- Cron job payloads (the scheduler stores its own model reference)
- Model allowlist (enforced by crons, bypassed by interactive sessions)
Changing the main config does not propagate to the other three. This is OpenClaw config drift in action. Your crons fire with stale models, time out on a model that no longer exists or isn’t loaded, fall back to a paid API provider, and burn credits you thought you eliminated.
The allowlist trap: The model allowlist is enforced by cron jobs but NOT by interactive sessions. You’ll switch to a new model, test it interactively, see it work perfectly, and walk away confident. Then your crons fail with “model not allowed” because you never added the new model to the allowlist. No error in the dashboard. No notification. Just silent failures and an API bill.
The fix: Patch all four stores atomically, then restart the gateway. Order matters: restart AFTER patching. The gateway writes in-memory state to disk on shutdown, so if you restart first, it overwrites your changes.
It took us 8 script iterations across multiple incidents to reliably patch all four stores. The model toggle workflow is not a single config change. It’s a coordinated update across multiple files with a specific execution order.
Lesson: If OpenClaw is using the wrong model on cron jobs, don’t just check the main config. Check session state files, cron payloads, and the allowlist. The discrepancy is almost always between stores.
Silent Heartbeat Failures: The Missing File Nobody Documents
What you see: Your agent’s heartbeat stops firing. Logs show nothing. Config looks correct. The doctor command reports no issues.
Why it happens: A required file (models.json) is missing from the agent directory. OpenClaw silently skips heartbeat execution rather than logging an error. Everything looks correct. Nothing tells you it’s broken.
We spent 4+ hours on this one. Checked config syntax, restarted the gateway, modified heartbeat intervals, added Telegram bindings, created a dedicated workspace. None of it worked. The fix took 30 seconds: copy models.json from a working agent’s directory.
Here’s the timeline:
- Hour 0: Noticed heartbeat not firing despite valid config
- Hour 1-3: Tested config changes, hot reloads, restarts. No effect.
- Hour 4: Compared the broken agent’s directory to a working agent, file by file
- Fix: One missing file. Copied it. Heartbeat fired within minutes.
Every agent directory needs these files for heartbeat execution:
SOUL.md(agent identity)models.json(provider configuration)auth-profiles.json(authentication store)
Missing any of these causes silent failure. Not “error and retry.” Not “warning in logs.” Silent. The heartbeat just never runs. If your OpenClaw heartbeat is not working, check these files first.
Broader lesson: OpenClaw has several “required but undocumented” files. When something silently fails, compare a working agent’s directory to the broken one. The difference is usually a missing file, not a config mistake.
Gateway Race Condition: Why Your Config Edits Disappear
What you see: You edit a config file while the gateway is running. Your changes work briefly, then disappear. Or they never take effect at all.
Why it happens: The gateway loads session state into memory at startup and periodically syncs it back to disk. When you edit files on disk, the gateway’s in-memory state overwrites your changes within seconds.
This is not a bug. It’s architecture. The gateway owns those files. You are a guest editing them.
Why this matters for model switching: If you change model config and don’t restart the gateway, it overwrites your changes from its in-memory state. Then you assume the change “didn’t work” and start debugging the wrong thing. You’re not looking at a broken config. You’re looking at a config that keeps getting reverted by the process that owns it.
The fix: Stop the gateway. Patch files. Start the gateway. That’s the only reliable sequence. Never edit config files while the gateway process is running.
If you docker self-host OpenClaw, bind mounts into the container’s config directory let you patch from the host. That alone makes a self-hosted deployment worth it over cloud platforms where you’re stuck with their own config tools.
When Agents Modify Their Own Config Files
What you see: Config files contain model names that don’t exist, API endpoints that were deprecated, or references to CLI tools the agent can’t access.
Why it happens: Given enough autonomy, agents hallucinate capabilities and write them into their own config files. This isn’t theoretical. We watched it happen. An agent decided it had access to tools it didn’t have, wrote those tools into its config, and broke its own execution environment.
The fix: two-layer defense.
Layer 1: Prompt rules. Add explicit rules to your agent’s instructions prohibiting config file modification. Put them in HARD-RULES.md or the equivalent enforcement file.
Layer 2: File permissions. chmod 444 on critical workspace files. Capabilities files, memory configs, skill definitions. The agent gets “Permission denied” when it tries to write.
The chmod trap: You can’t lock everything. The gateway actively writes to auth-profiles.json (credential sync on every session init), models.json (provider config resolution), and auth.json (plugin SDK auth storage). Is it safe to chmod config files in OpenClaw? Only workspace files. Gateway-managed files must stay writable at 644.
We learned this the hard way. We applied chmod 444 to everything, including gateway-managed files. Both agents broke immediately with EACCES errors on session init. The fix was restoring 644 on models.json and auth-profiles.json while keeping 444 on workspace files.
The rule: Lock what agents write. Don’t lock what the gateway writes.
Upgrade-Induced Config Drift: What Breaks When You Update

You update OpenClaw to a new version. The gateway starts. No errors. Everything looks fine. Then, hours or days later, you notice behavior degrading. Per-agent settings you configured weeks ago have no effect. Heartbeat intervals reset to defaults. Or worse: “gateway token mismatch” and agents can’t authenticate at all.
Why it happens: OpenClaw’s config schema changes between versions. Keys that were valid become silently invalid. New required fields appear without migration warnings. Gateway tokens may need regeneration after major version jumps.
We navigated 3 platform upgrades in 10 days. The Clawdbot-to-OpenClaw rebrand, then two subsequent version updates. Each one introduced subtle config drift that didn’t surface immediately.
The silent part: The gateway starts without errors. openclaw doctor --fix is the only tool that reveals stale keys. Your per-agent thinking level override? Silently dropped after the upgrade. Custom compaction settings? Gone. Browser profile defaults? Reset. You don’t notice until an agent starts behaving differently and you can’t figure out why.
The compounding effect: This is what makes OpenClaw upgrade breaking changes dangerous. Upgrade drift activates every other gotcha in this post. Stale model stores (Section 1) get worse when the allowlist schema changes. Heartbeat files (Section 2) may need new required fields. Hot reload behavior (Section 7) changes between versions. One upgrade can silently break three systems at once.
The fix:
- Before upgrading: Snapshot your entire
~/.openclaw/directory. A simplecp -ris fine. You want a rollback path. - After upgrading: Run
openclaw doctor --fiximmediately. It identifies and removes invalid keys that the new version silently ignores. - Check the changelog for new required config fields. Not everything gets auto-migrated.
- If authentication breaks: Regenerate the gateway token. Token format changes between major versions. GitHub Discussion #4608 confirms this is a widespread pain point after the Clawdbot-to-OpenClaw migration.
- Test cron jobs explicitly. Interactive sessions may work while crons fail on the new schema.
Lesson: Treat every OpenClaw update as a potential config migration event. The update itself takes 30 seconds. The silent config drift it introduces can take days to fully surface.
Cost Optimization That Actually Works

Here’s the silent cost failure: you switch to local models to save money. But stale cron configs keep firing paid API calls (Section 1). Heartbeats routed to local models fail silently when the model is unloaded (Section 2). Agents appear dead with no error. The “optimization” costs you more than what you saved.
OpenClaw cost optimization that works starts with one question: which tasks actually need expensive models?
Per-task model tiering:
| Task Type | Model Tier | Why |
|---|---|---|
| Utility crons (indexing, monitoring) | Free local (Ollama) | Pure procedure, no reasoning needed |
| Heartbeat/keepalive | Cheapest API tier | Just confirms alive. Must be reliable. |
| Standard analysis | Mid-tier API | Good balance of capability and cost |
| Complex reasoning | Top-tier API | Strategy reviews, multi-step planning |
The heartbeat routing rule: Don’t route heartbeats to local models. If your local inference server is down or the model isn’t loaded, heartbeats fail silently and agents appear dead. Use a cheap API model for heartbeats. It’s always available. The reliability is worth the fraction of a cent.
Context window right-sizing: We dropped from 32k to 24k tokens and saved VRAM. Why? The platform capped context at 24k anyway. The extra 8k was allocated but never used. Check your platform’s actual context limit before over-allocating.
Model pruning: We recovered 178GB of disk space by removing unused models from our local inference server. If you’re running Ollama, run ollama list and delete anything you haven’t used in a week.
Real cost trajectory: From $4+/day running everything on paid API, to $2-3/day with tiered routing, to near $0/day with local models handling routine tasks and API reserved for complex work. Start with per-task tiering, not a wholesale switch.
Hot Reload vs. Restart: Know the Difference
OpenClaw hot reloads most config changes without a gateway restart. But “most” is doing heavy lifting in that sentence.
What hot reloads (no restart needed):
- Browser profiles (CDP URLs, profile names)
- Heartbeat intervals
- Model parameters
- Agent bindings (Telegram, Discord channels)
What requires a restart:
- Gateway binding/port changes
- Major structural changes to agent configuration
The silent failure trap: Invalid config keys prevent hot reload from executing. You add a setting to a per-agent config block, save the file, check the logs. No reload happened. No error either.
The problem: some settings only work at the global agents.defaults level, not per-agent. Per-agent overrides for thinking level, browser profile defaults, and compaction settings are silently ignored. The gateway doesn’t warn you. It just skips the reload.
The diagnostic tool: Run openclaw doctor --fix. It finds and removes invalid config keys. If you’ve been troubleshooting a setting that “isn’t working,” this command will tell you whether the key was valid in the first place.
The schema gotcha: The config schema is stricter than it appears. Keys that look reasonable (thinkingDefault, browser, compaction at the agent level) are silently invalid. The docs don’t always specify which level each setting supports. When in doubt: set it in agents.defaults, test, then try moving it per-agent.
Key Takeaways
- Config drift is the biggest silent failure. OpenClaw stores models in four places. Change one, the other three stay stale. Patch all four atomically.
- Missing files cause silent heartbeat death. No errors, no logs. Check
models.jsonexists in every agent directory. - Never edit config while the gateway is running. It overwrites from memory. Stop, patch, start.
- Lock workspace files, not gateway files.
chmod 444on capabilities and skills. Leavemodels.jsonandauth-profiles.jsonwritable. - Treat every update as a config migration. Snapshot before, run
doctor --fixafter. One upgrade can silently break three systems. - Don’t route heartbeats to local models. Use cheap API for reliability. Silent heartbeat failure is worse than a fraction of a cent.
- Run
openclaw doctor --fixwhen things silently fail. Invalid config keys are more common than you think.

FAQ
Why is my OpenClaw heartbeat not firing?
The most common cause is a missing models.json file in your agent directory at ~/.openclaw/agents/{id}/agent/. OpenClaw silently skips heartbeat execution when this file is absent. No errors appear in logs and the doctor command won’t flag it. Verify your agent directory contains three files: SOUL.md, models.json, and auth-profiles.json. Compare your broken agent directory to a working one file by file. We spent 4+ hours debugging this before discovering the 30-second fix.
Why do OpenClaw config changes not stick after restart?
The gateway loads session state into memory at startup and periodically writes it back to disk. If you edit config files while the gateway is running, your changes get overwritten from in-memory state within seconds. The correct workflow: stop the gateway completely, make your edits, then start it again. Editing while running is futile because the gateway considers itself the owner of those files.
How do I fix OpenClaw model not allowed errors?
Add every model you use to the model allowlist in your main config. The allowlist is enforced by cron jobs but not by interactive sessions. This means you can test a model change interactively, see it work, and assume everything is fine. Then your crons fail with “model not allowed” because the allowlist wasn’t updated. Always test model changes by triggering a cron job, not by running an interactive session.
Why does OpenClaw ignore my config file changes?
OpenClaw stores model configuration in four separate locations: the main config, session state files, cron job payloads, and the model allowlist. Changing the main config alone does not propagate to the other three stores. Your cron jobs keep firing with the old model reference, time out, and fall back to a paid API provider. Patch all four stores, then restart the gateway. This is different from the race condition issue (above), where the gateway overwrites your changes from memory.
How do I switch OpenClaw models without breaking cron jobs?
Update all four model stores in this order: main config file, model allowlist, session state files for active cron sessions, and cron job payloads. Then restart the gateway. Restart must come AFTER patching because the gateway dumps in-memory state to disk on shutdown. Verify the switch by triggering a test cron, not an interactive session. The allowlist is only enforced during cron execution.
What breaks when you update OpenClaw?
Config schema changes between versions. Keys that were valid become silently invalid: per-agent thinking level overrides, custom compaction settings, browser profile defaults. The gateway starts without errors, so the drift is invisible until behavior degrades. Gateway tokens may also need regeneration after major version jumps (GitHub Discussion #4608 documents this after the Clawdbot-to-OpenClaw migration). Before upgrading, snapshot ~/.openclaw/. After upgrading, run openclaw doctor --fix to find and remove stale keys. Test cron jobs explicitly, because interactive sessions may work fine on the new schema while crons fail silently.
Is it safe to chmod config files in OpenClaw?
Only workspace files. Files like capabilities.md, skill definitions, and memory configs are safe to lock with chmod 444. But models.json, auth-profiles.json, and auth.json must stay writable at 644. The gateway writes to these files on session init, credential sync, and config hot-reload. Locking them causes EACCES errors that silently break agent sessions.
How do I reduce OpenClaw API costs with local models?
Implement per-task model tiering. Route utility tasks (indexing, monitoring) to free local models via Ollama. Keep heartbeats on the cheapest API tier (never local, because downtime causes silent failures). Use mid-tier API for standard analysis and top-tier for complex reasoning. Right-size context windows to match the platform’s actual limit. Prune unused models from your inference server to free VRAM. We went from $4+/day to near $0/day with this approach.
Why is OpenClaw using the wrong model on cron jobs?
Cron jobs bake the model reference at creation time into their payload. When you change models in the main config, existing crons keep using the old model. They time out, fall back to a paid API, and burn credits silently. Update cron job payloads directly, not just the main config. Then restart the gateway to prevent the in-memory state from reverting your changes.
How do I uninstall OpenClaw completely?
Stop the Docker container (docker compose down), remove the image, and delete the ~/.openclaw directory which contains all config, agent data, and session state. If you created bind mounts, clean up the mounted host directories. Remove any systemd services for browser automation or proxy forwarding.
