# OOM / Memory Pressure

## Symptoms
- Pod terminated with `OOMKilled` or JVM `OutOfMemoryError`
- Memory usage climbs until eviction
- Core dump or heap dump generated

## Checks
- Compare pod/container memory limits vs peak usage
- Inspect heap/thread dumps for leaks or unbounded caches
- Validate GC settings and memory flags
- Check for large payloads or unbounded batching
- Review sidecar/agent memory consumption

## Fix
- Right-size memory requests/limits
- Fix leaks or cap caches/buffers
- Split large batches/payloads
- Adjust GC or runtime memory options
