well, that didn’t go so well

Yesterday I updated my rails install on rubhub.com to the latest release. This was increadibly easy; just a case of typing ‘gems update’ and accepting the dependancy prompts. Unfortunately it seems to have caused some major stability issues. When I restarted apache things initially seemed fine, but then went downhill, with some requests being served normally, others timing out, and others throwing up nasty Linda Blair-esque errors. MySQL eventually consumed all of the RAM on the server and locked it up.

After I reverted to the earlier versions of the rails libraries, I still noticed some creeping memory usage; I’m not sure if this is a problem in ActiveRecord or in mod_ruby. I’ve shifted rubhub.com to running on ColdFusionMX on another host for the time being. The urls are almost idetical, but it’s difficult to make ColdFusion do the kind of things that you can do with mod_rewrite unless you have administrative control of the server.
