    Description

      Each time you deploy the ROOT.war to a running system there are more an more errors and eventually you get a OutOfMemoryException.

      The first reload gives this:

      [WARNING] [talledLocalContainer] Aug 6, 2012 8:48:35 PM org.apache.catalina.startup.HostConfig checkResources
      [WARNING] [talledLocalContainer] INFO: Undeploying context []

      By the third reload you get this:

      You can recreate this using cargo:run by:
      1) Start the server with "mvn cargo:run"
      2) Log into the portal
      3) Touch the ROOT.war file "touch target/tomcat6x/webapps/ROOT.war"
      4) Wait for the war to reload
      5) Refresh the portal page
      6) Repeat steps 3 - 5

      Eventually you get this error
