Java Database Connectivity (JDBC)

Hi

I have a java app running as a service and have noticed that it has been unexpectedly terminating quite a bit over the last month or so. Yesterday it happened twice, citing an exception in native code outside the VM. I really have no idea where to start debugging this. Below is what is in the log file that is generated when it terminates. Does anybody know why something like this would be happening? Looking at the stack trace, it looks like a strange place to be terminating? Have you come accross anything like this?

/Thanks

An unexpected exception has been detected in native code outside the VM.
