[mvapich-discuss] Error - vbuf not correct

[Liu Jianyu]

Hi,

Recently WRF V3.6.1 aborted with these error messages on OFA

    recv desc error, 10934
    recv desc error, 10934
    [5] Abort: vbuf not correct.
    at line 410 in file src/mpid/ch3/channels/nemesis/netmod/ib/ib_vbuf.c

Tried run WRF on TCP/IP with the same nodes like this without any problems

   MPICH_NEMESIS_NETMOD=tcp  mpirun -np 64 -ppn 8 -hostfile n064 ./wrf.exe

Wondering it may be hardware issue of IB.   But no idea how to identify the 
problem node.

Any comments ?

Appreciating your kindly help

Regards

Jianyu
