The problem was that we doubly decremented the active count on blocking receives that we stall to complete. This moved the active count into the negative. With a negative count for 'active' a message that should have been accounted for would be over looked. This then causes the bookmark exchange to post a drain for a message that was never posted, thus locking the protocol. By eliminating the decrement on the 'active' count when we attempt to post the drain message, we only the decrement this counter when the outstanding blocking recv completes during the stall operation.
