Hi,

I am trying to run a Job on parallel nodes using openmpi1.4.5 and ge2011.11,  job goes in Running state and then gets aborted.
After Job gets aborted, I get following error message on the primary node:

error: executing task of job 28561 failed: failed sending task to execd at punehpcdl01.wiprohpc.com: can't find connection

Or

error: executing task of job 28560 failed: failed sending task to execd at punehpcdl01.wiprohpc.com: can't find connection
--------------------------------------------------------------------------
A daemon (pid 20651) died unexpectedly with status 1 while attempting
to launch so we are aborting.

There may be more information reported by the environment (see above).

This may be because the daemon was unable to find all the needed shared
libraries on the remote node. You may set your LD_LIBRARY_PATH to have the
location of the shared libraries on the remote nodes and this will
automatically be forwarded to the remote nodes.
--------------------------------------------------------------------------

mpirun noticed that the job aborted, but has no info as to the process
that caused that situation.
--------------------------------------------------------------------------
mpirun: clean termination accomplished

Is this mpi issue ? Please suggest how do I resolve this connection issue between nodes.

Thanks & Regards,
Aditi
