Connect or not CannotConnectException that is the question ?

[ecatum]

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.

It looks like you're using a rather old version of Remoting. If so, you should probably upgrade.
