Config Rollback Watchdog Gateway: Combine Health Checks with Automatic Rollback

A Reddit user on r/openclaw proposes a mechanism to prevent the OpenClaw gateway from being stuck in a boot loop due to faulty configuration changes. The idea combines a watchdog with automatic config rollback — all implemented outside of OpenClaw itself.

How It Works

• A watchdog monitors the gateway's port responsiveness.
• If the port becomes unresponsive, the watchdog automatically restarts the gateway.
• If the gateway fails to start 5 times in a row, the watchdog rolls back the configuration to the previous known-good version before attempting another restart.

This ensures that a bad config change doesn't permanently brick the gateway. The rollback happens externally, so OpenClaw's own boot logic is untouched.

Why This Matters

Users report that OpenClaw sometimes modifies its own configuration, causing the gateway to fail on the next startup. A simple restart watchdog loops forever if the config is broken. Adding a fail counter with automatic rollback breaks the loop.

The poster asks the community: "Do you have such mechanisms? Maybe better ones?"

This is a practical, low-overhead approach for production gateways where uptime matters. The external watchdog pattern means it can be implemented with systemd, Docker healthchecks, or a custom script — no need to modify OpenClaw internals.
