    Connect or not CannotConnectException that is the question ?

      Hi,

      I m develloped an application which use jboss remoting and rmi.

      For the server, I implement ServerInvocationHandler.
      For the client, I use org.jboss.remoting.Client to communicate with the server.

      I periodically make invocation from clients to the server and release the connection using disconnect().

      Problem :
      After a perdiod of time, the server no longer accepts client connections and clients catch this exception :

      11:12:55,515 ERROR [STDERR] org.jboss.remoting.CannotConnectException: Error making invocation in RMI client invoker.

      Can it be the Client connection which aren't correctly released ?
      Have somebody indications where in jboss I can search the origin of the problem ?

      Thanks a lot.
