Profiling Node.js Memory Leaks in Production Environments
A walkthrough of heap snapshot analysis, core dump tracing, and diagnosing native memory growth in V8.
Diagnosing memory leaks that only occur under heavy production load requires strategic profiling. We examine capturing core heap dumps without blocking execution loops.
By analyzing heap growth patterns and tracing closure scopes in Chrome DevTools, we resolved a native memory leak in a long-running socket handler.
