I have refined the test data some more, writing a perl program to take
the monitor exit and enter output data and print out only the cases
where numEnters != numExits.
I ran the program in the debugger until it froze and collected the data,
along with the stack traces on the threads mentioned in the data. I did
this twice.
Hypothesis: I believe that deadlock is occurring and I have a hunch that
there are some valuable clues in the data below. Can someone please
look at the stack traces and see if they can spot the deadlock? Is this
the right forum for this kind of information? I'm really stuck here.
My MO is to collect enough information for someone who is an expert to
gain insight.
