The stack traces in both cases are similar and indicate to me that the processes have ended up executing data. However by the time I get to disassemble the code referred to by the backtrace the code isn't there any longer.
is most of the cases, it means that the program is no longer running (it may have been killed by the other program)
What's my best bet for tracking this down?
as the processes seem to be furtive, using relay traces (and friends) may be a better bet to locate the issue, and then perhaps set the bp where needed
A+
