Hi David,
The following might be of use to you:
We recently had a struts-based application that crashed seemingly randomly, and after
a lot of work and debugging we tracked it down to a bug in the JVM (we were using
Sun's 1.4.1 JDK ). It was reproduceable on several platforms (HP-UX, Linux, win2k).
We were not getting any dumps either on some of the platforms, the process seemed to
just hang.
Note: testing showed IBM's JDK didn't exhibit this behaviour, but Blackdown did.
A workaround for us was to add the following parameters to Sun's 1.4.1 JVM:
-Xint Operates in interpreted-only mode.
-Xrs Reduce usage of operating-system signals by Java
virtual machine (JVM).
A fix for us was to upgrade to JDK 1.4.2
For more info, try posting the VM messages you are receving here. They may not be very
helpful to you (or me:-) but perhaps somebody knowledgeable on the list might be able
to make sense of them.
Regards,
Morgan

- please could anyone point me in the right direction to try and get to the bottom of
this. Is it easy to run tomcat in a debugger so we can catch what happens?
Many thanks,
David
