The backtraces from the console are in the sequoia_ion_console.txt attachment.</p> <p>No further info to go on at this time. Admins rebooted node before we got to investigate.</p> Lustre 3.5.53-3chaos, BG/Q ppc64 client LU-2141 Soft lockup at mount time Story Blocker Resolved Duplicate Alex Zhuravlev Christopher Morrone Wed, 10 Oct 2012 18:56:11 +0000 Tue, 13 Nov 2012 19:34:04 +0000 Tue, 13 Nov 2012 17:10:10 +0000 Lustre 2.4.0 0 6 <p>Any ideas Alex?</p> <p>It is happening again, which many Sequoia client nodes hanging. This is a major problem for sequoia.</p> <p>The soft lockup messages are exactly the same, and the node is completely unresponsive.</p> <p>Chris, have you observed this since 16 Oct?</p> <p>I am not aware of any. This is probably lower priority at the moment than other tickets.</p> <p>Likely a duplicate of <a href="https://jira.whamcloud.com/browse/LU-2263" title="CPU Soft Lockups due to many threads spinning on import lock on Sequoia IO nodes" class="issue-link" data-issue-key="LU-2263"><del>LU-2263</del></a>.
