## Statements (checkable)
0. The official OpenClaw troubleshooting docs list reason=heap_threshold as a log or CLI signature.  [✓0 ✗0]
1. Documented meaning: lower prompt/session pressure or reduce concurrent work first. For a managed service, compare the configured controls and install-time recommendation in Gateway heap: from openclaw gateway status with the runtime measurement. Reinstalling preserves existing stored heap settings; it does not automatically replace an older value with the current recommendation.  [✓0 ✗0]

## Fix
