Better not to touch MRs involved in a flush or post error until the Send and Receive Queues are drained and the transport is fully quiescent. Simply don't insert such MRs back onto the free list. They remain on mr_all and will be released when the connection is torn down. I had thought that recycling would prevent hardware resources from being tied up for a long time. However, since v5.7, a transport disconnect destroys the QP and other hardware-owned resources. The MRs get cleaned up nicely at that point.
