Simply run "MDSCOUNT=4 ONLY=300 sh sanity.sh" 2/3 times, will cause memory corruption. So this patch needs to get into 2.8. </p> <p>Agree. I also have seen sanity test 300k take out my nodes.</p> <p>Di,</p> <p>Why wasn't the stupid test disabled 4+ weeks ago?</p> <p>Oleg Drokin (oleg.drokin@intel.com) merged in patch <a href="http://review.whamcloud.com/16889/" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/16889/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-7318" title="OUT: dynamic reply buffer" class="issue-link" data-issue-key="LU-7318"><del>LU-7318</del></a> out: dynamic reply size<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 12d6356a48de70922975e38451059211c753252e</p> <p>Landed for 2.8</p> Blocker LU-4215 Related LU-6831 Development Rank 1|hzxqvj: Rank (Obsolete) 9223372036854775807
