Code or Matlab causing segvault errors - Matlab Version 7.14

One of my researchers is receiving the following error while calling the parallel function. This started recently and we've tried some basic troubleshooting. This is running on a RHEL 5.9 64 bit Dell server.

------

Error using parallel_function (line 589) The session that parfor is using has shut down

Error in MCpost (line 27) parfor a = 1:length(vamp) % amp = vamp

The client lost connection to lab 5. This might be due to network problems, or the interactive matlabpool job might have errored.

------

Whenever he runs this job, I can see there are segfault errors in the logs.

Is this a problem with his code or physical memory?

Any advice or direction would be appreciated!!

This indicates that the worker MATLAB is crashing. Do you have a reproduction that you can post here? Do you have the full stack trace? Are MEX functions involved?

Thanks Edric. I'll get that info asap.
