Sorry, there was a "no" missing in this sentence, sorry for the confusion.

Hmm, OK, so your PA terminated due to overloading your CPU. 

Unfortunately it is not easy to figure out what is going on. PA
probably spins in some kind of busy loop. The question is which one
that is. A good way to find out which one would be running a profiler
on PA.

Do you think you'd be able to do that? I can give a few hints but it's
no fun unless you already know you way around with low-level debugging
tools like gdb.
