While sizing the heap for 32-bit Java applications on AIX, you can sometimes run into situations where a segment is claimed by two or more parts of the process simultaneously. This article shows how to detect this situation by using a well-established set of applications as examples, and we also show the reasoning behind the configuration changes suggested to avoid this situation.
