[mvapich-discuss] MVAPICH2-1.9 assertion in ch3_smp_progress.c

[Adam T. Moody]

Hello MVAPICH team,
One of our applications is tripping up an assertion in MVAPICH2-1.9.  
This is the error that we get:

Error rank 79: Fatal error in MPI_Testall:
Other MPI error, error stack:
MPI_Testall(243)...: MPI_Testall(count=10, ...) failed
MPIDI_CH3I_Progress_test(474)
MPIDI_CH3I_SMP_read_progress(972)
MPIDI_CH3I_SMP_readv_rndv(4286)..: recv_buf->busy == 1

Have you seen this error before?  Do you know what might cause this?

Disabling shared memory seems to be a work around.
Thanks,
-Adam
