[02/27/2014 12:36:47] FATAL error on process 0
Proc 0: Unable to stat file [/mnt/lustre/d0.metabench/CREATE_MD_008.000/nSUFhBISq]: No such file or directory
--------------------------------------------------------------------------
mpirun has exited due to process rank 0 with PID 29305 on
node client-32vm5 exiting improperly. There are two reasons this could occur:

1. this process did not call "init" before exiting, but others in
the job did. This can cause a job to hang indefinitely while it waits
for all processes to call "init". By rule, if one process calls "init",
then ALL processes must call "init" prior to termination.

2. this process called "init", but exited without calling "finalize".
By rule, all processes that call "init" MUST call "finalize" prior to
exiting or it will be considered an "abnormal termination"

This may have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).
