[mvapich-discuss] messege truncated

[nilesh awate]

Hi all,
I  am using  mvapich2-1.0.3  with  dapl  interconnect (its a proprietary  nic & dapl library)
I got following error while running pallas over (amd dual core) 5 nodes cluster.

Fatal error in MPI_Recv:
Message truncated, error stack:
MPI_Recv(186)..........................: MPI_Recv(buf=0x7fff24744cec, count=952788905, MPI_INT, src=2, tag=1000,MPI_COMM_WORLD, status=0x7fff24744cd0) failed
MPIDI_CH3U_Post_data_receive_found(243): Message from rank 2 and tag 1000 truncated; 4 bytes received but buffersize is -483811676
rank 0 in job 2  test01_40634   caused collective abort of all ranks
  exit status of rank 0: killed by signal 9


will you suggest where we should look for solving above error ?
what can we interpret from above message ? 

wating for reply
thanking 
Nilesh
