Help to analyze MessageCancelledException

[ymss]

Our JBoss AS 7 server came up with following error from time to time:

2014-05-02 18:37:13,443 348744523 ERROR [org.jboss.as.protocol] (Remoting "management-client" task-4 JBAS012102: Failed to close resource org.jboss.remoting3.remote.InboundMessage$3@319af32b: org.jboss.remoting3.MessageCancelledException

I can't figure out why, could someone help to analyze the possible cause? Thanks a lot!
