The best way is to connect it to a serial console to grab the output.
Depending on the state of the machine, you may even be able to grab that
with 'dmesg' or the syslogs (although it's not likely to have made it to the

What you did makes sense to me.

If it is a stack overflow, then yes, it _could_ be related, but I'm not
going to blame that just yet ;)
