Is it possible to disable crash dump files?

16 views (last 30 days)
Hi
I am using matlab-7.14r2012a on a Linux setup and I am running compiled Matlab code. I want to avoid that Matlab creates crash dump files in my home directory. Normally, Matlab creates a $HOME/matlab_crash_dump.XXXX whenever it crashes. I tried redirecting the dump using the "-R -logfile -R filename " option at compile time which works fine but the crash dump is not redirected but duplicated, meaning that the content of matlab_crash_cump.XXXX is appended to filename . Is it possible to completely redirect the crash dump or even disable it?
Regards
PS: I know that it would be better to locate the reason for the crash, I am on it but the program is rather large so it takes a lot of time.

Dear Benjamin Did you manage to find the solution, I am having an exact issue like you.

Hi Pratul. I did not really find a solution, just a workaround. Ever since posting this question I have been using a cronjob to periodically delete the dump files (as Jan suggested, too). However, for me this is only a work around as the real issue is actually high file server load when hundreds of Matlab processes crash simultaneously (I use condor to run tons of jobs simultaneously) and, hence, hundreds of dump files get written concurrently.

Crash dump files can contain sensitive information. They should be created reliably even if the code does not run as expected. Therefore the home directory is the best location to store these files in.
I'm using a cron job to remove all but the last dumb file.

There may be a way for you to disable the crash dump files for your tasks, I suggest contacting support directly. The methods of controlling what, when and where crash dump files are created very with MATLAB versions.
