Root cause analysis (user source code) is in progress.</p> <p>The workload is (for one user), under a directory (where the ldlm_lock is held during the crash):</p> <ul> <li>mkdir temp1 (crash lock on temp1 parent)</li> <li>create many files under temp1</li> <li>create zip file from temp1 contents (ie rename from zip temporary file to final zip name, zip internals...)</li> <li>unlink files inside temp1</li> <li>rmdir temp1</li> <li>in temp1 parent dir, some noise, many truncate on somes files</li> <li>on one file 18000 close in 2 minutes</li> <li>on 5 fid in the same directory, 10 truncates + close in loop until crash</li> </ul> <p>It is not hopefully a valid workload for us...</p> <p>Finally on our side, we are not in DoM path but we hit due to this patch <a href="https://review.whamcloud.com/47487" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/47487.</a></p> <p>Fix now.
