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 and even with
the latest weekly-build.
Tested on Debian Strecth, Ubuntu 16.04 and Centos 7.

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

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 !

test streamlined, commit bisected, issue created:
https://github.com/varnishcache/varnish-cache/issues/2782

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 !

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

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

Hello,
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.
