i'm using cocoon 2.01 with jboss 2.4.4/tomcat 3.2.3 and have
experienced almost the same problem. but i dont know if its cocoon
related or jboss/tomcat...

when i restart jboss the cocoon app is correctly answering requests

the problem occurs, when i deploy my app i think more then ten times
without restarting jboss/tomcat.
