I have similar problem in which hypersonic database as queue. Initially the messages shall be dequeued at good speed. However with time the dequeue process become extremely slow and finally come to a halt. Lots of time I got to see the "Exiting on IOE" error on my server.log. However I was told that we can safely ignore this error. Is this true? regards Shantanu Chauhan View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3987796#...
