- The statistics-2014 core finished processing after five hours, so I started processing the statistics-2013 core on DSpace Test
- Since I was going to restart CGSpace and update the Discovery indexes anyways I decided to check for any straggling upper case AGROVOC entries and lower case them:
```
dspace=# BEGIN;
dspace=# UPDATE metadatavalue SET text_value=LOWER(text_value) WHERE resource_type_id=2 AND metadata_field_id=57 AND text_value ~ '[[:upper:]]';
UPDATE 164
dspace=# COMMIT;
```
- Run system updates on CGSpace (linode18) and reboot it
- I had to restart Tomcat once after the machine started up to get all Solr statistics cores to load properly
- After about ten more hours the rest of the Solr statistics cores finished processing on DSpace Test and I started optimizing them in Solr admin UI
## 2020-11-10
- I am noticing that CGSpace doesn't have any statistics showing for years before 2020, but all cores are loaded successfully in Solr Admin UI... strange
- I restarted Tomcat and I see in Solr Admin UI that the statistics-2015 core failed to load
- Looking in the DSpace log I see:
```

```
- Seems that the core gets probed twice... perhaps a threading issue?
- The only thing I can think of is the `acceptorThreadCount` parameter in Tomcat's server.xml, which has been set to 2 since 2018-01 (we started sharding the Solr statistics cores in 2019-01 and that's when this problem arose)
- I will try reducing that to 1
- Wow, now it's even worse:

```
- Could it be because we have two Tomcat connectors?
- I restarted Tomcat a few more times before all cores loaded, and still there are no stats before 2020-01... hmmmmm
- I added a [lowercase formatter to OpenRXV](https://github.com/ilri/OpenRXV/commit/3816b9b3f3d9182d2ba1a899c1017c5895a59dee) so that we can lowercase AGROVOC subjects during harvesting
