Hi Vidhya,
A control socket is replaced if the client is listening for a ping from the server and the ping does not arrive. Originally, JBossMessaging had turned off the pinging, but there has been some confusion lately. I would suggest going to $JBOSS_HOME/server/$CONFIG/deploy/messaging/remoting-bisocket-service.xml and adding the lines
<attribute name="pingFrequency" isParam="true">214748364</attribute>
<attribute name="pingWindowFactor" isParam="true">10</attribute>
which will turn off pinging.
