Regression (worked before, now fails)

Beta release blocker

No

Summary

The logs show what happened:

At 21:21:27, the gateway's own liveness monitor detected a severe event-loop freeze: eventLoopDelayMaxMs=23622ms, eventLoopUtilization=0.98 (98%) 24 seconds later at 21:21:51, the gateway's built-in self-preservation mechanism sent itself SIGTERM with "restarting" It then waited up to 5 minutes to drain active work, but didn't finish in time, so systemd killed it after 30s and restarted it This is OpenClaw's own liveness watchdog doing exactly what it's designed to do — recover from event-loop starvation. The gateway saw its event loop was 98% utilized with 23-second delays and decided to restart. Version went from 2026.5.5 → 2026.5.6.

Steps to reproduce

Not sure just work then you get the message gateway is being restarted.

Expected behavior

Do we really need to say that rebooting and hanging is not expected behavior?

Additional information

I hope the OpenClaw team can get its act together. I am seriously thinking that doing an engineering course and making my own version would be quicker than you fixing these stability issues.
