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
