## 2015-12-05
- CGSpace has been up and down all day and REST API is completely unresponsive
- PostgreSQL idle connections are currently:
```
postgres@linode01:~$ psql -c 'SELECT * from pg_stat_activity;' | grep cgspace | grep -c idle
28
```
- I have reverted all the pgtune tweaks from the other day, as they didn't fix the stability issues, so I'd rather not have them introducing more variables into the equation
- The PostgreSQL stats from Munin all point to something database-related with the DSpace 5 upgrade around midlate November
