Java Out of Memory
Resolving The Problem
IBM WebSphere included SDK 1.6 SR9 has some memory leaks.
These memory leaks and out of memory problems have been experienced in Maximo environments using WebSphere 7.1 with Java SDK 1.6 SR9. As a result, Maximo is recommending to upgrade WebSphere to WebSphere 7.0 fixpack 35 or higher along with Java SDK.
Since the problem is in the Java SDK, it is required to update the SDK along with WebSphere.
