I suppose you are using JBM 1.4.1.GA that comes with JBOSS AS 5. It doesn't look like a jboss messaging issue. Can you please give the full stack trace of the exception and also your queue configuration in destinations-service.xml so we can have a better understanding of this issue? also can you please post to AS forum also to get more help?
