In this situation the message is freed<br/> without detaching the MD. As a result, requests do not receive their<br/> unlink events and these requests are stuck forever.</p> <p>This issue was discovered while testing the MR routing feature under LNet router failure conditions.</p> <p>Bug was introduced by the LNet health feature commit 70616605dd44be37068f4e1a4745a2f8b90eb1f5 <a href="https://review.whamcloud.com/32764" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/32764</a></p> LU-12199
