[mvapich-discuss] mvapich crash with error 12

[Ben]

I'm getting a random crash on occasion in a code with the message

[0->6150] send desc error, wc_opcode=0
[0->6150] wc.status=12, wc.wr_id=0x28193068, wc.opcode=0, 
vbuf->phead->type=25 = MPIDI_CH3_PKT_RNDV_REQ_TO_SEND
[4979] Abort: [] Got completion with error 12, vendor code=0x81, dest 
rank=6150
  at line 583 in file ibv_channel_manager.c

I saw another post suggesting playing with the

>/  MV2_DEFAULT_TIME_OUT
/>/  MV2_DEFAULT_RETRY_COUNT
/>/  MV2_DEFAULT_RNR_RETRY


/

Although I don't see these as options in the user guide. Does any any 
more insight on what this error message means?

I'm using mvapich 1.8.1
