I'm not so sure: he's getting what looks like a clean shutdown, not a VM
crash or OOME or anything like that.

If it were on Linux and he were running out of memory and the process
just disappeared, I would blame the OOM killer. I'm pretty sure that
when windows runs out of memory, Windows itself goes down. In any event,
the clean shutdown is very unexpected given all the other information we
have.

Martin, you don't have anything running in your webapp that monitors
memory usage and does a clean shutdown when memory is running low, do
you? (I imagine you would have mentioned that if you knew about it!)

He said he's using the default, so the JVM is choosing the heap size for
him. He's probably getting something like a 64MB or 128MB heap.
