It got worse earlier this week when I couldn’t ssh to my Dreamhost account at all.
Staff informed me that I had 35 zombie Ruby processes running (from my Typo installation).
Just doing a normal kill wasn’t enough to kill some of them, but kill -5 xxxxx seems to do the job.
I also deleted my frozen copy of Rails in ./vendor and am using the newly upgraded version on the Dreamhost server.
The good news is that I’m back to FCGI and hopefully the fixes in the current Rails candidate will help.
