I’m running mvapich2 1.9 compiled with thread multiple enabled.  I was hoping someone might be able to explain the following error message I’m receiving.  Based on the error message alone, seems like it should’ve been ok?  Thanks.

In: PMI_Abort(1, Fatal error in PMPI_Test:

Message truncated, error stack:

MPIDI_CH3U_Buffer_copy(64): Message truncated; 16 bytes received but buffer size is 16

)
