Tomcat 6 No Available Handlers

We are running GW 12.0.2 on SLES 11 SP1. This particular server holds a secondary domain, a GWIA, and WebAccess. While searching for an answer as to why the WebAccess quits responding I found the following errors in the catalina.out file.

ERROR: No handler is available for the action [Folder.List.Open]

This keeps repeating itself. I'm not too familiar with tomcat but it would appear that something is calling a Folder.List.Open action that is not supported? Anyone have clue as to why I see this?
