Atmire responded about the issue with duplicate data in our Solr statistics
They noticed that some records in the statistics-2015 core haven&rsquo;t been migrated with the AtomicStatisticsUpdateCLI tool yet and assumed that I haven&rsquo;t migrated any of the records yet
That&rsquo;s strange, as I checked all ten cores and 2015 is the only one with some unmigrated documents, as according to the cua_version field
I started processing those (about 411,000 records):

<li>Udana emailed me yesterday to ask why the CGSpace usage statistics were showing &ldquo;No Data&rdquo;
<ul>
<li>I noticed a message in the Solr Admin UI that one of the statistics cores failed to load, but it is up and I can query it&hellip;</li>
<li>Nevertheless, I restarted Tomcat a few times to see if all cores would come up without an error message, but had no success (despite that all cores ARE up and I can query them, <em>sigh</em>)</li>
<li>I think I will move all the Solr yearly statistics back into the main statistics core</li>
</ul>
</li>
<li>Start testing export/import of yearly Solr statistics data into the main statistics core on DSpace Test, for example:</li>
</ul>
<pre tabindex="0"><code>$ ./run.sh -s http://localhost:8081/solr/statistics-2010 -a export -o statistics-2010.json -k uid

</code></pre><ul>
<li>I deployed Tomcat 7.0.107 on DSpace Test (CGSpace is still Tomcat 7.0.104)</li>
<li>I finished migrating all the statistics from the yearly shards back to the main core</li>
</ul>
<h2 id="2020-12-05">2020-12-05</h2>

<li>Looking into the statistics on DSpace Test after I migrated them back to the main core

<li>All stats are working as expected&hellip; indexing time for the DSpace Statistics API is the same&hellip; and I don&rsquo;t even see a difference in the JVM or memory stats in Munin other than a minor jump last week when I was processing them</li>
</ul>
</li>
<li>I will migrate them on CGSpace too I think
<ul>
<li>First I will start with the statistics-2010 and statistics-2015 cores because they were the ones that were failing to load recently (despite actually being available in Solr WTF)</li>

<li>I sent some feedback to Atmire
<ul>
<li>They responded with an updated CUA (6.x-4.1.10-ilri-RC7) that has a fix for the duplicates processor <em>and</em> a possible fix for the database locking issues (a bug in CUASolrLoggerServiceImpl that causes an infinite loop and a Tomcat timeout)</li>
<li>I deployed the changes on DSpace Test and CGSpace, hopefully it will fix both issues!</li>

<li>I decided to cherry-pick the following two patches from DSpace 6.4 into our <code>6_x-prod</code> (6.3) branch:
