+- Peter pointed out that Solr stats are only showing 2019 stats
+  - I looked at the Solr Admin UI and I see:
+
+```
+statistics-2018: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Error opening new searcher 
+```
+
+- As well as this error in the logs:
+
+```
+Caused by: org.apache.lucene.store.LockObtainFailedException: Lock obtain timed out: NativeFSLock@/home/cgspace.cgiar.org/solr/statistics-2018/data/index/write.lock
+```
+
+- Strangely enough, I *do* see the statistics-2018, statistics-2017, etc cores in the Admin UI...
+- I restarted Tomcat a few times (and even deleted all the Solr write locks) and at least five times there were issues loading one statistics core, causing the Atmire stats to be incomplete
+  - Also, I tried to increase the `writeLockTimeout` in `solrconfig.xml` from the default of 1000ms to 10000ms
+  - Eventually the Atmire stats started working, despite errors about "Error opening new searcher" in the Solr Admin UI
+  - I wrote to the dspace-tech mailing list again on the thread from March, 2019
