I've attached the crash report and a graph of the CPU usage. You can see where the CPU usage is "normally" pegged at 100%, then is spikes and crashes.
This crash also broke my auto-restart script. I'm using the exit code of the java process to detect crashes. On a non-zero exit code, I restart the server. On a zero exit code, I leave it shut down. A crash like this should exit with some sort of non-zero exit code.
