Question

I have a rails app on heroku that users log in to. I periodically get this exception:

Assuming you saw this recently, this is due to a recent bit of high-priority maintenance work to enable continuous backups on shared databases -- involving a server restart. You shouldn't worry about this error, provided it does not reproduce. I don't think that's very likely, so happy hacking!

I had this error happen to me. My Application server had an open connection to the database. In my SSH terminal I added an ipaddress to the ph_hba.conf file and restarted the postgreSQL server.

That is when this error showed up. I refreshed my web page one time and the error was gone.
