Thanks a lot. I have read the Issue.I make sure my remoting-bisocket-service.xml have the line and the remoting version is 2.2.2sp7: | <!-- The maximum time to wait before timing out on trying to write a message to socket for delivery --> | <attribute name="callbackTimeout">10000</attribute> | I will try to set prefetchSize smaller to verify. Why the https://jira.jboss.org/jira/secure/attachment/12317850/stack_traces.zip can not download.I need stack trace to confirm there are the same problem.
