    Dear Guys,
    For some weeks now, I often have severe memory problems with Fiddler. Fiddler takes all memory, then all other applications need to access the pagefile and quickly the system becomes unusable. This happens every two days or once a week or so. It happens today and it happened two days ago.
    * I don't stream any audio or video.
    *  "Keep only" is set to 100.
    * To me, it seems this is somehow correlated to Windows downloading some update packages. Not sure, though. 
    Fiddler Version:
    v4.6.20171.7553
    Built: Fr, 27. Jan 2017
    64-bit AMD64, VM: 49,0mb, WS: 84,0mb
    .NET 4.6.2 WinNT 10.0.15063.0
    If client aborts while streaming, finish if session visible

    !memory in QuickExec Box gives:

    This could well be. But my problem isn't solved.

    I've posted my problem also in that thread on May 30st. I've reposted as a separate thread (this one) as nobody seemed to react on that post.
    Inbetween people took notice of my post in the other thread, so this thread here could probably be closed.

    Sorry for crossposting and best regards!
