Mac OS X 10.5.4 EXC_CRASH (SIGQUIT)

Post by rdforbes » Thu Jul 31, 2008 10:12 pm

My iMac is recording crashes everyday with the Folding app; although it seems to be running just fine and is returning results to you on a regular basis. I use InCrease.

Here's a snippet from the error log (CrashReporter):

I'd rather see the FAHlog.txt file ... :roll:

SIGQUIT is a standard method used to get the cores to quit and to write a core-dump. I suspect is is used by that particular version of MPI to get a status report once processing is complete. If that guess is correct, it's not something I'd call an error. The guys who wrote that version of MPI would be able to give you an accurate answer. Since (apparently) it doesn't show up in FahLog, it's not something that FAH cares about.

You are correct, there are no obvious errors showing in the FAHlog.txt file.

While FAH isn't seeing errors, Folding is nevertheless filling the Mac's CrashReporter Logs

Here's the related snippet from the FAHlog:
