If the network and/or server are busy, it could be that the default timeout (1000 ms) is too stringent. You can set the org.jboss.remoting.ConnectionValidator timeout by passing ConnectionValidator.VALIDATOR_PING_TIMEOUT (actual value "validatorPingTimeout") with a string value such as "5000" in either 1. the InvokerLocator used to create the org.jboss.remoting.Client, 2. the configuration map used to create the Client, or 3. the metadata map passed to Client.addConnectionListener().
