+- Help Francesca from Bioversity generate a report about items they uploaded in 2015 through 2018
+- Linode emailed me to say that CGSpace (linode18) had high CPU usage for a few hours this afternoon
+- Looking at the nginx logs around that time I see the following IPs making the most requests:
+
+```
+# zcat --force /var/log/nginx/*.log /var/log/nginx/*.log.1 | grep -E "19/Oct/2018:(12|13|14|15)" | awk '{print $1}' | sort | uniq -c | sort -n | tail -n 10

+- 5.9.6.51 is MegaIndex, which I've seen before...

+- I was going to try to run Solr in Docker because I learned I can run Docker on Travis-CI (for testing my dspace-statistics-api), but the oldest official Solr images are for 5.5, and DSpace's Solr configuration is for 4.9
+- This means our existing Solr configuration doesn't run in Solr 5.5:
+
+```
+$ sudo docker pull solr:5
+$ sudo docker run --name my_solr -v ~/dspace/solr/statistics/conf:/tmp/conf -d -p 8983:8983 -t solr:5
+$ sudo docker logs my_solr
+...
+ERROR: Error CREATEing SolrCore 'statistics': Unable to create core [statistics] Caused by: solr.IntField
+```
+
+- Apparently a bunch of variable types were removed in [Solr 5](https://issues.apache.org/jira/browse/SOLR-5936)
+- So for now it's actually a huge pain in the ass to run the tests for my dspace-statistics-api
