• CGSpace went down
• Looks like DSpace exhausted its PostgreSQL connection pool
• Last week I had increased the limit from 30 to 60, which seemed to help, but now there are many more idle connections:

$ psql -c 'SELECT * from pg_stat_activity;' | grep idle | grep -c cgspace
78

• For now I have increased the limit from 60 to 90, run updates, and rebooted the server

• CGSpace went down again
• Getting emails from uptimeRobot and uptimeButler that it's down, and Google Webmaster Tools is sending emails that there is an increase in crawl errors
• Looks like there are still a bunch of idle PostgreSQL connections:

$ psql -c 'SELECT * from pg_stat_activity;' | grep idle | grep -c cgspace
96

• For some reason the number of idle connections is very high since we upgraded to DSpace 5
