How are you handling log rotation? I was encountering really strange, non-logged 500 errors every week because I used some bad log rotation advice from the Rails wiki. I don't have the link handy since it seems the wiki is down right now, but I found this thread:
http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/218107 The jist: Don't let Logger rotate the log. Instead, let Rails log as much as it wants to into production.log and rely on some out-of-process log rotation daemon (eg, logrotate). Or, switch to some ruby-based logging solution that works when more than one process tries to rotate the same log file. I personally use the former.
