IBM WebSphere - Core Dump

[Travis Kline]

Hi all,
After migrating from WebSphere 3.5 to 4.0.5 our application is crashing when under a heavy load. I was hoping to get a core dump after the app crashed to find some clues as to what may be causing the problem. Unfortunately, WebSphere does not seem to provide a core dump.
How and when exactly does WebSphere administer a core-dump? Does the developer need to add any specific error/exception handling to receive a core-dump? Any advice/help would be greatly appreciated....
thanks,
Travis
