Thank you very much Guillaume. For now, I'll postpone our migration to Varnish 6.

I'll try to see what I can find once I have more time, unless someone looks into it first

    Hi,

    Yesterday, I also tried manualy with varnish 6.1 and the first
    time I believed it was working. But after 1 or 2 minute (I think
    to a timeout) I had the same error : "Child not responding to CLI,
    killed it."

    Thanks Guillaume for your help !

    Regards,

    Confirmed using a Dockerfile (weirdly it worked the first time
    when I did it manually), looks like we have a bug. I'll look into it

        Hello,

        Based on this blog article :
        https://info.varnish-software.com/blog/one-vcl-per-domain
        I've been
        using multiple VCL with Varnish 5.2 without any problem.
        However, I don't manage to get it working with Varnish 6.

        I tried with the latest stable version on packagecloud.io
        <http://packagecloud.io> and even with
        the latest weekly-build.
        Tested on Debian Strecth, Ubuntu 16.04 and Centos 7.

        Did anyone manage to get it working with varnish 6 ?

        Thank you.
