I've been trying to set up JVisualVM to monitor a number of JVMs that are running as a part of an application server install. These JVMs are on JDK5, which can be monitored with JVisualVM, but for some reason every time I started it up, it crashed with a seg fault.
This is the error I was getting every time...
# A fatal error has been detected by the Java Runtime Environment:

So it turned out the issue was that I was using a 64bit JVisualVM to monitor a 32bit JVM. Since the bitness was not matched, a seg fault occurred. The fix is to use a 32bit JVisualVM to monitor a 32bit JVM.
