      patch https://review.whamcloud.com/#/c/18347 introduced a bug. Basically you're negotiating the number of fragments and then explicitly setting the max_send_wrs according to that number. This patch introduces the logic where if you fail to allocate the qp then you reduce max_send_wrs by quarter, but that could cause a problem where not enough wrs are available under heavy load, if you're sending multiple fragments.
