There are several options for post send failures:
1) the SQ is full (all of the WR in this Queue are outstanding)
2) bad opcode is being used
3) number of sge in the WR > number of sge of the SQ that the QP was
created with
4) if inline flag was set: the message size is too big to be sent as inline

I believe that your problem is 1) ....
