I am using JBOSS 4.2.2 and EJB 3.0. I am accessing an EJB remotely from a client. I wanted to make a test run and made my calls within a while loop

Ex:

while (true) {
    // Call Remote Bean
}

It run well for some time and then it gave the following exception 

ex=Can not get connection to server. Problem establishing socket connection for InvokerLocator [socket://x.x.x.x:3873/]
org.jboss.remoting.CannotConnectException: Can not get connection to server. Problem establishing socket connection for InvokerLocator [socket://x.x.x.x:3873/]

Is there any way to configure the number of connections in the pool? Or whether there is any limitation on the number of calls to the EJB within a specified time limit?
