Occasinnal CPU stuck on WAIT while watching live TV

1st Official Post

    Ok my setup is a Server running Libreelec on a Pi 4 4gb. Its running tvheadend latest version. 9.1.901.444

    Once in a while I am watching live tv and the image if frozen for between 5-30 seconds and after it starts playing again.

    This happens mostly when watching live TV.

    I installed the necessary addons to start a basic diagnostic to understand whats going on when its frozen.

    When running normally, I see in my Network I/O using NMON that its transmitting fine and all my CPUS are mostly IDLE.

    When it freezes, Half my CPU's are on WAIT and the Transmitted info is at 0kb/s.

    I checked the logs and nothing was printed at that time.

    No recording were active at that time and Timeshift is active.

    Any idea on what to check next?

    Thanks
