Scott,
Yes, I've noticed that to. Not sure why yet. Not having any other war deployed other then Red5 and oflaDemo would make way more stable. Also, if you previously deployed the echo.war then you might want to run the server, deploy the ear and while deployed rename the red5.deployed to red5.remove to force JBoss to clean the deployment directory. Then, redeploy it again by renaming the file to red5.dodeploy (make sure that only the red5 and oflaDemo wars are deployed).
Cheers,
B.
