+- 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 mid–late November
