kill -3 does not produce a javacore

This is a sporadic problem I run into when kill -3 does not generate a javacore and the process has to be terminated. The first thing to check is the service release of the JVM and ensuring the JVM is at the correct level with the corresponding level of WebSphere Application Server. In some cases I have installed later fixes than those that have been tested with WebSphere Application Server.

Another suggestion a colleague of mine had was to generate an AIX core of the process (make sure the ulimits for file and core are properly set to unlimited but you already knew that because you followed the installation instructions for WebSphere Application Server). I don't remember which kill signal needs to be sent but I'm sure a Goggle search will reveal that answer.
