If you have a firewall sits between your client and server and it is configured to kill some connections idle for a period of time, you need to adjust your remoting configurations, esp those: <!-- the following parameters are useful when there is a firewall between client and server. Uncomment them if so.-->                <!--                          <attribute name="numberOfCallRetries" isParam="true">1</attribute>                <attribute name="pingFrequency" isParam="true">214748364</attribute>                <attribute name="pingWindowFactor" isParam="true">10</attribute>                <attribute name="generalizeSocketException" isParam="true">true</attribute>                --> -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/559264#559264] Start a new discussion in JBoss Messaging at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
