Andreas,
Thanks for the reply. I think that you are referring to the lustre
server and client rather than the mpi server (mother superior) and
the clients in your response below.
We are seeing many messages of this type which correspond to the job
being ended in PBS and a message sent to the job std out "FATAL from
PE 34: open_param_file: Input file INPUT/HIM_input does not exist."
I think you are saying that the lustre server is unresponsive, but
would like to confirm. We're not seeing many other messages which we
can tie to the job exit.

This is -4 = -EINTR (from /usr/include/asm/errno.h), so it just means
your job was killed with CTRL-C when it was stuck. The server was
not responsive to the client and should be investigated.
Cheers, Andreas
