Redmine

I'm running Redmine on Dreamhost shared hosting @ http://redmine.elsewares.org to manage my clients, who are all over the US. When I first installed it, I was able to set up fine. Since then, however, the wait times have gotten longer until now the site times out almost every time it's accessed. I checked the production log, and saw:

The site is running on a Dreamhost shared hosting server with Phusion Passenger. I have no idea why this is happening, and restarting the application doesn't seem to help. I've also deleted the production log, since that was getting large-ish (236k) and I thought that was the issue. Two tickets to support later, they can't seem to reproduce the problem, but all of my clients (from California to Atlanta, literally) can't use the site, so it must not be a network issue.

Any suggestions?
