<li>After logging in via XMLUI and clicking the Listings and Reports link from the sidebar it redirects me to a JSPUI login page</li>
<li>If I log in again there the Listings and Reports work&hellip; hmm.</li>

<li>Tim Donohue responded to my thread about the cookies on the dspace-tech mailing list
<ul>
<li>He suspects it&rsquo;s a change of behavior in Tomcat 8.5, and indeed I see a mention of new cookie processing in the <a href="https://tomcat.apache.org/migration-85.html#Cookies">Tomcat 8.5 migration guide</a></li>
<li>I tried to switch my XMLUI and JSPUI contexts to use the <code>LegacyCookieProcessor</code>, but it didn&rsquo;t seem to help</li>

<ul>
<li>Day two of CGSpace AReS meeting in Amman
<ul>
<li>Discuss possibly extending the <a href="https://github.com/ilri/dspace-statistics-api">dspace-statistics-api</a> to make community and collection statistics available</li>
<li>Discuss new &ldquo;final&rdquo; CG Core document and some changes that we&rsquo;ll need to do on CGSpace and other repositories</li>
<li>We agreed to try to stick to pure Dublin Core where possible, then use fields that exist in standard DSpace, and use &ldquo;cg&rdquo; namespace for everything else</li>
<li>Major changes are to move <code>dc.contributor.author</code> to <code>dc.creator</code> (which MELSpace and WorldFish are already using in their DSpace repositories)</li>
</ul></li>
<li>I am testing the speed of the WorldFish DSpace repository&rsquo;s REST API and it&rsquo;s five to ten times faster than CGSpace as I tested in <a href="/cgspace-notes/2018-10/">2018-10</a>:</li>

<ul>
<li>Day three of CGSpace AReS meeting in Amman
<ul>
<li>We discussed CGcore and decided some action points</li>
<li>We discussed branding of AReS tool</li>
</ul></li>
<li>Something happened to the Solr usage statistics on CGSpace
<ul>
<li>I looked on the server and the Solr cores are there (56GB!), and I don&rsquo;t see any obvious errors in dmesg or anything</li>
<li>I see that the server hasn&rsquo;t been rebooted in 26 days so I rebooted it</li>
</ul></li>
<li>After reboot the Solr stats are still messed up in the Atmire Usage Stats module, it only shows 2019-01!</li>
</ul>
<p><img src="/cgspace-notes/2019/01/solr-stats-incorrect.png" alt="Solr stats fucked up" /></p>
<ul>
<li>In the Solr admin UI I see the following error:</li>

<pre><code>statistics-2018: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Error opening new searcher
