Java heap corruption and crash in WebSphere Application Server

Troubleshooting


Problem

You have Java™ heap corruption and your WebSphere Application Server crashes frequently in random thread stacks. You are missing AIX 5.3 APAR IZ52719. The same issues have also been noticed in AIX 6.1.

Symptom

WebSphere Application Server frequently crashes in random thread stacks that are inconsistent. There will be frequent crashes in application code, garbage collection, Java code, and so on. The crashes will not be related to each other and will not show any consistent patterns. These random crashes are common with memory corruption issues.

This issue occurs after security patches for AIX 5.3 and AIX 6.1 have been applied to a server.
