[mvapich-discuss] error closing socket at end of mpirun_rsh

[Mark Potts]

Hi,
    Can you explain the functioning of the wait_for_errors() function
    in .../mpid/ch_gen2/processes/mpirun_rsh.c in MVAPICH 0.9.9 and
    what might be happening to cause even small (2 process jobs) to
    frequently fail with the message
       "Termination socket read failed: Bad file descriptor" .
    I'm not clear what the socket s/s1 does and therefore how we
    could be getting the above error message upon reading either
    "flag" or "local_id" in this code.

    This error occurs frequently but not for every job and is
    emitted following full, proper termination of the processes on
    the client nodes. We are using MVAPICH 0.9.9 ch_gen2.

    Thanks.
             regards,
