same here on x86_64 with intel 9.1, and openmpi.

ezad,
since you are using separate diretory for temporary files,
are you sure that you don't accidentally run two jobs with
the same 'prefix'?
also i noticed that the job creates a lot of disk i/o.
i would suggest to check the machine hosting the disk(s)
for i/o errors in the kernel log.

cheers,
   axel.
