MAnagers:
THanks for the quick and helpful responses. There were basically two
types of response:
1) Send a BUS signal to the process. This will cause a core dump, and
the core file can be analyzed using gdb.
2) Attach the debugger to the running process using: gdb executable pid
We are going to try getting a core file sent back to us to try and figure
out where we are stuck. The original question is attached.
BTW, when I passed these answers, there were several folks here who said
that they figure this would work fine. Guess I need to get a better feel
for who been informed of things here before I bother you good folks
again with something we should have been able to do ourselves.
Many thanks to the following for taking the time to help:
