 - Now the cores seem to load, but I still see an error in the Solr Admin UI and I still can't access any stats before 2018
 - I filed an [issue with Atmire](https://tracker.atmire.com/tickets-cgiar-ilri/view-ticket?id=685), so let's see if they can help
+- And since I'm annoyed and it's been a few months, I'm going to move the JVM heap settings that I've been testing on DSpace Test to CGSpace
+- The old ones were:
+
+```
+-Djava.awt.headless=true -Xms8192m -Xmx8192m -XX:+UseConcMarkSweepGC -Dfile.encoding=UTF-8 -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=5400 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false
+```

+- And the new ones come from Solr 4.10.x's startup scripts:
+
+```
+    -Djava.awt.headless=true
