Alex is right. "invokerDestructionDelay" affects the creation of invokers on the client side, and setting "isParam" to "true" causes the "invokerDestructionDelay" parameter to be included in the InvokerLocator, which means it can be seen by the client. I should tell you, though, that the use of "invokerDestructionDelay" may not help you when you're using the http transport. See the thread "Socket keep alive with client EJB and RMI over HTTP" (http://www.jboss.org/index.html?module=bb&op=viewtopic&t=137758&postdays=0&postorder=asc&start=0) in this forum. Unfortunately, I don't have any good answers right now.

I'm not sure why increasing "callbackPollPeriod" didn't have an effect, but you probably don't want to be using nonblocking mode anyway, and "callbackPollPeriod" is ignored in blocking mode. For that reason, I would suggest upgrading JBM. Until recently it was necessary for the client code (JBM in this case) to specify the blocking mode when calling org.jboss.remoting.Client.addListener(), but JBREM-1084 "Allow CallbackPoller to access Client and InvokerLocator parameters" will allow org.jboss.remoting.callback.CallbackPoller to get the blocking mode directly from the InvokerLocator if you add the parameter "useAllParams" to the InvokerLocator with the value set to "true"; i.e., add | <attribute name="useAllParams" isParam="true">true</attribute> | to remoting-http-service.xml. That feature doesn't exist in a released version of Remoting yet, but, if you're interested, I could attach a preview jboss-remoting.jar to JBREM-1084.
