Adrian, Again, thanks for your help. I've tried the runGarbageCollection invokation from the MBean inspector. It did reduce the current memory consumption, but didn't cause the 'desired' crash.
I guess I should clarify what I mean by 'crash' because that is a rather overloaded and abused word. First, let me describe the operating environment for JBoss. Much like VMWare allows one to run virtual machines inside of a windows or linux host operating system, the mainframe we have (z/800) has the ability to run multiple linux images at the same time. (Technically, the mainframe is divided into multiple logical partitions.) JBoss is running in one of the linux images. At some point, and what causes this is entirely unclear, the instance consumes 100% of the allocated CPU. Once this happens, terminals stop responding. Technically speaking, there is no 'crash' (with log entries, and all the nice dump files). The only evidence I have right now is the output of top that was left (and pasted in the previous email). It seems to indicate that there's something funky going on with the java processes (since they were in a sleep state for a long time, and transitioned into a running state).

System.gc() is just a hint, the VM can ignore it. If the VM takes the hint it will do a full gc. You can do this from the jmx-console http://localhost:8080/jmx-console Look for jboss.system:type=Server then the operation runGarbageCollector() The fact that your OS's VM is crashing suggests a more serious issue.
