During openclaw gateway update to version 2026.3.12, the following errors occurred:
- Completion cache update failed with OOM error:
Completion cache update failed (<--- Last few GCs --->

Steps to reproduce
Update from 2026.3.11 to 2026.3.12 on a 2GB RAM VM

Update should complete without OOM errors.
Actual behavior
Update completes but completion cache update fails with heap memory error, and gateway refresh also fails. Service eventually restarts but completion cache may be in a corrupted state.
