Planned maintenance has been done but it did not solve the problem. So work will continue on this and a new time for trying updates will be announced asap.

qnetwork hibernate macos freezes



  • Hello,
    I have a mac application what polls with the qnetworkaccessmanager every minute to a server to get updates form him. this all works fine, up to the moment the mac goes into hibernate mode. If this happens, after a wakeup 90% of the time the application freezes completely and needs to be forced quit and restarted.
    What can cause this? It looks like there was going out a request shortly before the hibernate, what comes back (reply) when the mac woke up.

    I tried already to delete the qnam after wake up and create a new instance of it before a new request is send out, but here most of the time the app is also freezing

    with regards
    Georg

    Hi,

    By hibernate do you mean closing a MacBook Pro screen ? Or put it to sleep from the Apple menu ?

    In any case, can you reproduce that with a minimal project ?



  • I mean, the hibernate of a notebook what is not used after a defined time and goes to hibernate, or while closing the MacBook. Not sure if I can make here a small project to simulate this, will try

    You don't need to simulate, just have something that small and exhibit the same behavior.
