Jan 8, 2024 · In this article, we’ve explored the different memory areas of a Java process and a few tools to monitor memory usage. We’ve seen that Java memory usage is not just limited to the heap, so then we used jcmd to inspect and track the memory usage of the JVM.

Aug 25, 2023 · Managing the memory usage of a Java process running in a Kubernetes pod is more challenging than one might expect. Even with proper JVM memory configurations, OOMKilled issues can still...

Jan 2, 2025 · Java memory management is a fundamental concept that involves the automatic allocation and deallocation of objects, managed by the Java Virtual Machine (JVM). The JVM uses a garbage collector to automatically remove unused objects, freeing up memory in …

Java handles memory quite differently from what you might expect. When you set the -Xms and -Xmx paramters, you are telling the JVM how much memory it should allocate in the heap to start with and also how much it should allocate as a maximum.

The actual process may consume more memory. java.nio.ByteBuffer.allocateDirect() is a function/library, that is easily missed, and indeed allocated native memory, that is not part of the Java memory management.
