    Intermittently
    Sometimes overnight (Ie no interaction for hours)
    Sometimes on action <click>

    Normal is 50% memory used (50% == 4G), no swap (32G)
    I'm running vmstat to see if mem usage changes

    Background processes (video recording with gstreamer - heavily threaded) launched with startDetached continue running

    app is qmake c++ code with Qt6
    gstreamer renders in a QWidget.

    Any ideas on how i could track down. There is NO coredump.

      Hi,

      Which OS are you on ?
      If macOS, you could start by sampling your application to see if there's something unusual going on.
