Maybe MySql timeout? from mongrel faq 
Q. Mongrel stops working if it's left alone for a long time.
If you find that Mongrel stops working after a long idle time and
you're using MySQL then you're hitting a bug in the MySQL driver that
doesn't properly timeout connections. What happens is the MySQL server
side of the connection times out and closes, but the MySQL client
doesn't detect this and just sits there.
What you have to do is set:
ActiveRecord::Base.verification_timeout = 14400
Or to any value that is lower than the MySQL server's
interactive_timeout setting. This will make sure that ActiveRecord
checks the connection often enough to reset the connection.
