[xSocket-develop] XSocket non-blocking can't be established

[Steven Ma <ste...@em...>]

Dear sir,

We found that after a number of connections are established and then disconnected for a certain period of time, a new non-blocking connection can’t be established anymore. However, we are not sure about the timing of this period. It should be around 7 to 23 hours. According to xsocket source code, we go through the detail and we found that:

The program always stopped when calling connection.init(ioHandler) in Server.LifeCycleHandler.onConnectionAccepted(IoChainableHandler)

Below is the "Call Hierarchy" that we chase into:
IoAcceptor.accept()
  -> Server.LifeCycleHandler.onConnectionAccepted(IoChainableHandler)
    -> NonBlockingConnection.init(IoChainableHandler)
      -> NonBlockingConnection.init(IoChainableHandler, IIoHandlerCallback)
        -> IoSocketHandler.init(IIoHandlerCallback)
          -> IoChainableHandler.setPreviousCallback(IIoHandlerCallback)
          -> IoSocketDispatcher.register(IoSocketHandler, int)
            -> ... (we guess the program may be stopped in this method somewhere)

xsocket.connection.Server.java

public void onConnectionAccepted(IoChainableHandler ioHandler) throws IOException {

        // create a new connection
        NonBlockingConnection connection = new NonBlockingConnection(connectionManager, handlerAdapter.getConnectionInstance());

        // set default flush properties
        ………

        // initialize the connection
        connection.init(ioHandler);

        // set timeouts  (requires that connection is already initialized)
        ……..

        // set transfer rates
        ………
}

We are testing it under xsocket v2.5.4. I’d like to know how to solve or work around this problem. Thanks.

Regards,
Steven Ma
