500 error, no log files


A rails app that had been running smoothly for 2 months is suddenly
giving a 500 error. Unfortunately the production.log is not being
written to (the permissions seem to be fine) and the mongrel.log
doesn't offer any clues. I'm on a media temple GS for this particular
app. Any ideas?

I've done a lot of googling but can't seem to find anything.


Your host probably updated either Ruby, Rails or one of the gems you are using, making your app break. Bundler (http://github.com/wycats/bundler) is really nice to freeze gems into your app.
