Symptom & Impact

Java services terminate unexpectedly, causing request failures and repeated restarts.

Environment & Reproduction

Appears during load spikes or memory leaks in long-running JVM applications.

Root Cause Analysis

Heap allocation strategy and workload profile exceed available memory budget.

Quick Triage

Capture heap usage trends and identify whether leak or burst traffic drives growth.

Step-by-Step Diagnosis

Review GC logs, process memory maps, and container or host memory constraints.

Solution – Primary Fix

Tune JVM memory settings, patch leak sources, and adjust service resource limits.

Solution – Alternative Approaches

Scale horizontally or offload memory-intensive operations to separate workers.

Verification & Acceptance Criteria

No OOM crashes under expected load and GC behavior remains within baseline targets.

Rollback Plan

Revert JVM flags if changed GC settings introduce latency regressions.

Prevention & Hardening

Profile memory regularly and alert on sustained heap growth trends.

Related Errors & Cross-Refs

java.lang.OutOfMemoryError and Linux OOM killer process terminations.
