Troubleshooting
Problem
The WebSphere Application Server running within WebSphere Business Events V7.0 runs out of memory on HP-UX and Solaris platforms.
Symptom
The following error messages are seen in the logs:
- SystemErr.log:
[11/10/09 17:11:06:780 GMT] 00000010 SystemErr R Exception in thread "HAManager.thread.pool : 1" java.lang.OutOfMemoryError: PermGen space - SystemOut.log:

==> Performing default dump from com.ibm.ws.hamanager.runtime.DiagnosticMod :Tue Nov 10 17:09:11 GMT 2009
Cause
This error is because the default permanent generation parameter value is insufficient for holding class data and other long-lived resources.
Resolving The Problem
To avoid this error, follow these steps to set the JVM max perm size limit:
- From the WebSphere Application Server Administration Console, select Servers > Server Types > WebSphere Application Servers > <Server running WBE> > Server Infrastructure > Java and Process Management > Process Definition > Java Virtual Machine > Generic JVM arguments.
- Add -XX:MaxPermSize=1024M to the generic JVM argument to set the max perm size.
- Restart the application server.
- After tuning the heap sizes, monitor the system to make sure that paging does not occur.
