## 2019-01-16
- Day three of CGSpace AReS meeting in Amman
- We discussed CGcore and decided some action points
- We discussed branding of AReS tool
- Something happened to the Solr usage statistics on CGSpace
- I looked on the server and the Solr cores are there (56GB!), and I don't see any obvious errors in dmesg or anything
- I see that the server hasn't been rebooted in 26 days so I rebooted it
- After reboot the Solr stats are still messed up in the Atmire Usage Stats module, it only shows 2019-01!
![Solr stats fucked up](/cgspace-notes/2019/01/solr-stats-incorrect.png)
- In the Solr admin UI I see the following error:
```
statistics-2018: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Error opening new searcher
```
- Looking in the Solr log I see this:
```

```
- I found some threads on StackOverflow etc discussing this and several suggested increasing the address space for the shell with ulimit
- I added `ulimit -v unlimited` to the `/etc/default/tomcat7` and restarted Tomcat and now Solr is working again:
