OpenClaw Hang Caused System Freeze | Generated by AI
Here is a summary of why your system likely hung and what the logs revealed:
1. The Symptoms
- System Soft-Lock: Your computer became unresponsive, showing only a mouse icon on a black/frozen screen.
- Service Failure: SSH logins failed because the reverse proxy/forwarding to port
18789(OpenClaw) was refusing connections. - Recovery: A manual hard restart was required, which successfully brought services back online around 19:10 GMT+8.
2. The Likely Cause: OpenClaw Stalled
The evidence suggests OpenClaw (the gateway) hung first, which potentially starved the rest of the system or the GNOME desktop environment of resources:
- SSH Logs: Errors recorded as early as 17:34 show port
18789was already down, long before the full GUI freeze. - Failed Deliveries: After rebooting, OpenClaw found a message in its queue (
1b3ae44b...) that had failed its maximum retry limit (5/5). This suggests a “poison pill” message or a network hang during a Telegram/message delivery attempt might have caused the internal process to loop or block.
3. Other Contributing Factors
- Network/Proxy Issues: Services like
v2rayaandPackageKitrecorded numerous connection failures to127.0.0.1:7890right at startup, suggesting the local proxy (Clash/v2ray) takes a while to become stable, which can cause timeout-related hangs in other services. - NVIDIA Initialization: There were transient errors during boot where the second GPU failed to initialize, though it doesn’t appear to be the primary cause of the midday freeze.
4. Recommendations
- If it happens again: Try hitting
Ctrl+Alt+F3to jump to a text console. If you can log in there, runtopto see if anodeprocess is consuming 100% CPU. - Restart OpenClaw specifically: If you lose access to the UI but can still run commands, use
openclaw gateway restart. - Check the “Failed” folder: I can inspect
~/.openclaw/delivery-queue/failed/to see exactly what message was stuck if you want to identify the specific trigger.
