Spent 3 days debugging why our Kubernetes pods kept getting OOMKilled. Turns out memory limits need to account for JVM overhead, not just heap size. This guide saved me. Essential reading for anyone running Java in containers.

The OOMKilled rabbit hole is real. Now we always use tools like jstat to monitor actual memory usage before deploying.

Oh man, I spent a week on this exact issue. JVM memory overhead is no joke - always set limits 20-30% higher than heap.
