Cluster configuration, worked fine. After one node of the cluster was restarted, one of the portlets does not work. Everything else seems to work fine.
Root cause seem to be:
javax.faces.FacesException: java.lang.IllegalStateException: The window output stream used
Trace begins with the following, and is very long:
Cause: javax.portlet.PortletException: Error process faces request
Message: Error process faces request
StackTrace:
javax.portlet.PortletException: Error process faces request

Any hint what might have gone wrong?
