I have been looking at the code for core/mad.c and in timeout_sends(),
the mad_send_wr is removed from the list of pending sends and

the list of pending sends.
This seems wrong to me. Either there should be no increment, or
there should be a decrement when the WR is removed from the list.
Also, I think there may be a dependency on whether
mad_send_wr->timeout is zero or not.
The increment is done because the MAD has been reposted to the QP and will be
referenced by a CQ entry. The decrement happens once the completion occurs.
This should be correct.
