This one has bothered me for a bit, and I have very little to go on. I'm running JRuby-1.1RC2 + Ruby 2.0.2 + Warbler 0.9.3 + Tomcat 5.5.16.
I have two things that periodically happen; at some point, after restarting tomcat, the webapp will refuse to respond properly. I will get an error about a file not being found; it is usually followed by an error that indicates that a ruby class wasn't found in the file that actually is in. For example, I'll get the message "Expected <path to file which I've removed>/database/fmm_sybase.rb to define Database::FmmSybase. Of course, it is defined in that file.
In addition, I've had a number of times where Tomcat shuts itself down. Only once do I recall seeing a message being logged (in essence saying that it was pausing the http traffic). It's generally after a stop like that that the first problem then occurs after trying to restart Tomcat. Generally, the only way to get the app running again is to actually reinstall the web app. I've tried just removing the exploded view of the app, and having tomcat redeploy, but generally that doesn't work.
Has anybody else seen anything like this? I'll put more logging in place to try and identify whatever the error is, but ... any suggestions?
Thanks!
