## 2017-11-29
- Linode alerted that CGSpace was using 279% CPU from 6 to 8 AM this morning
- About an hour later Uptime Robot said that the server was down
- Here are all the top XMLUI and REST users from today:
```

```
- PostgreSQL activity shows 69 connections
- I don't have time to troubleshoot more as I'm in Nairobi working on the HPC so I just restarted Tomcat for now
