&gt; &gt; core on Linux<br>
&gt; &gt;<br>
&gt; &gt; Facing the same problem in the following runs as well,<br>
&gt; &gt;<br>
&gt; &gt; 1)<br>
&gt; &gt; <a href="https://build.gluster.org/job/rackspace-regression-2GB-triggered/18767/console" rel="noreferrer" target="_blank">https://build.gluster.org/job/rackspace-regression-2GB-triggered/18767/console</a><br>
&gt; &gt; 2) <a href="https://build.gluster.org/job/regression-test-burn-in/546/console" rel="noreferrer" target="_blank">https://build.gluster.org/job/regression-test-burn-in/546/console</a><br>
&gt; &gt; 3) <a href="https://build.gluster.org/job/regression-test-burn-in/547/console" rel="noreferrer" target="_blank">https://build.gluster.org/job/regression-test-burn-in/547/console</a><br>
&gt; &gt; 4) <a href="https://build.gluster.org/job/regression-test-burn-in/549/console" rel="noreferrer" target="_blank">https://build.gluster.org/job/regression-test-burn-in/549/console</a><br>
&gt; &gt;<br>
&gt; &gt; Last successful burn-in was: 545 (but do not see the test having been<br>
&gt; &gt; run here, so this is inconclusive)<br>
&gt; &gt;<br>
&gt; &gt; burn-in test 544 is hung on the same test here,<br>
&gt; &gt; <a href="https://build.gluster.org/job/regression-test-burn-in/544/console" rel="noreferrer" target="_blank">https://build.gluster.org/job/regression-test-burn-in/544/console</a><br>
&gt; &gt;<br>
&gt; &gt; (and at this point I am stopping the hunt for when this last succeeded :) )<br>
&gt; &gt;<br>
&gt; &gt; Let&#39;s know if anyone is taking a peek at the cores.<br>
&gt;<br>
&gt; hm. Not familiar with this test. Written by Pranith? I&#39;ll look.<br>
<br>
</div></div>We are doing lookup everywhere, and building up a dict of the extended attributes of a file as we traverse each sub volume across the hot and cold tiers. The length field of one of the EC keys is corrupted.<br>
<br>
Not clear why this is happening.. I see no tiering relationship as of yet, its possible the file is being demoted in parallel to the foreground script operation.<br>
<br>
The test runs fine on my machines.  Does this reproduce consistently on one of the Jenkins machines? If so, getting onto it would be the next step. I think that would be preferable to masking this test case.<br>
