We're continually getting the following error in my log file: 2009-10-19 12:48:49,893 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/].[Status Servlet]]

We don't have any idea as to what is causing this exception or how to stop it from being generated. It also seems to persist across restarting of the server.
