signal.h or errno.h ?

So periodically I get lockups and I can't pin-point them. Just now I tried removing a season pass and after twenty minutes of "thinking" it reboots..and the logs says:

so, is signal 2 the same as just reg errors or do they have their own? If it's just a SIGINT is there a way to force a core file when it panics? I haven't done much kernel/process debugging in linux to know how to force it to dump core so I can see where the issue is.

I don't think this issue is related to my previous lock ups though..but I'm getting ready to try and delete the season pass again..and I'm assuming I"ll get the same behaviour, I'd like to get the dump of it. i'll see if i can get an strace dump of it to get some idea before hand.

TIA for any feedback,
^Derrick
