Why Is My Java Service Stalling? Uncovering GC, Safepoint, and Log4j2 Bottlenecks

After weeks of investigation, this post details how intermittent request timeouts in a high‑concurrency Java service were traced to frequent JVM stop‑the‑world pauses caused by GC, safepoint logging, biased lock revocation, and Log4j2’s synchronous logging, and outlines the steps taken to diagnose and resolve the issue.
