Hi

We have been running a high load application on 3 x Freebsd 5.4 uniprocessor jdk
1.5.0p2 systems for the last 4 months with out any problems.

Two weeks ago a new system was added. FreeBSD 6p1 jdk 1.5.0p2. The application
ran for a day and then the VM crashed. After the VM crash the system was stable
for a week. Yesterday we had a system hang. The console was unresponsive and I
had to power cycle the system. It might be a hardware fault, but the system runs
stable when the java app is not started.

If possible, can someone please look at the jdk crash log? I don't know what to
look for and if someone can shed some light on the reason for the crash it would
be much appreciated.

Regards
Conrad
