[Nek5000-users] MPI strange error

[nek5000-users at lists.mcs.anl.gov]

Howdy Neks!

Anybody seen this kind of failure before?

MPI_Recv(187).......................: MPI_Recv(buf=0x7fffa1440cf8, 
count=4, MPI_BYTE, src=MPI_ANY_SOURCE, tag=1, comm=0x84000004, 
status=0x7fffa1440640) failed
MPIDI_CH3U_Request_unpack_uebuf(600): Message truncated; 32 bytes 
received but buffer size is 4

I've run many other cases on the exact same computer with no issue.  Ran 
the bad case on a different computer, and got the same error. I assume 
the issue is specific to that case, but don't quite understand how.  Any 
ideas?

Thanks,
Andrew
