Hi all,

We are experiencing frequent exceptions from MPI_Probe recently. Does anybody know what cause might be for this exception and what I can do to track down the cause?

MPI_Probe(113).......................: MPI_Probe(src=MPI_ANY_SOURCE, tag=MPI_ANY_TAG, comm=0x84000002, status=000000033FA217C8) failed

MPIDI_CH3I_Progress(402).............:

MPID_nem_mpich2_blocking_recv(905)...:

MPID_nem_newtcp_module_poll(37)......:

MPID_nem_newtcp_module_connpoll(2656):

gen_read_fail_handler(1145)..........: read from socket failed - The specified network name is no longer available.

Our cluster has MPICH2 1.4.1p1 and Windows Server 2008 R2 installed on 22 slave nodes and 1 master node.

Thanks,

Feng
