[mvapich-discuss] FATAL event IBV_EVENT_QP_LAST_WQE_REACHED

[Nathan Dauchy]

Pierrick, All,

We recently upgraded to OFED-1.2 (mvapich-0.9.9) and are now getting an
error that looks similar to yours:

[0:w72] Abort: [0] Got FATAL event IBV_EVENT_QP_LAST_WQE_REACHED,
code=16 at line 2552 in file viacheck.c

Did you ever find a solution?  (I can't find one in the archives.)

Can someone explain what the IBV_EVENT_QP_LAST_WQE_REACHED error means?
  I can't find any clues in the source, and have been unable to turn up
any relevant docs either.

Thanks for any help and clues you can offer!

Regards,
Nathan
