We have been experiencing an issue in our environment (Jruby 1.4, Rails
2.3.5, Tomcat 5.5, Java 1.6) where duplicate session_ids are being
in the sessions table. We are assuming the only way this can happen is
2 sessions are created at the exact same time on 2 different machines
have 10 app servers running with config.threadsafe! on). Has anyone
encountered this issue? It seems the “randomness” of the session
is not unique enough and doesnt account for multiple machines (tomcat
the ip of the machine as well i believe).
