I have a Grails application (v. 2.2.5) deployed in a production environment. I had some issues with a dashboard page with several graphs loading the data via AJAX. Most of the graphs show up correctly but after a week or so of it being deployed some of the graph's disappear. If I clear out tomcat's work directory, and restart all the graphs show again. How is the cache getting messed up?
-EDIT- Using the Grails Resources Plugin for compressing and bundling resources.
