client GUI hangs after server application is paused and resumed

  • I have a client application which has two threads running:

    1. Woker thread and main event loop thread(handling the GUI)

    The worker thread communicated with server application using TCP/IP .
    The GUI thread receives and sends information from and to worker thread using signals and slots.

    When I pause my server application- both client side threads worker and GUI work fine.
    When I resume my server application after the pause- worker thread sends/receives data but GUI does not respond. Server application is working fine. I suspect that the main eventloop probably exited??

    What exactly happens when you resume the server? It looks like your GUI thread is blocked or waiting for something.
