Regression (worked before, now fails)

Beta release blocker

No

Summary

Using a Gemini model in OpenClaw can cause the system to enter a stuck/looped state that only clears after a gateway restart.

Steps to reproduce

Not fully minimized yet, but the issue appears when switching to / running Gemini models.

Expected behavior

In the same installation, other active models (for example gpt-5.4) continue serving requests normally, so Gemini model requests should also complete or fail gracefully without requiring a gateway restart.

Actual behavior

After using a Gemini model, the system becomes unresponsive / stuck in a loop and does not recover until the gateway is restarted.

Additional information

I can try to collect more diagnostics on the next reproduction if you tell me which logs / debug flags would be most useful.
