Thanks for the feedback. We tried 6.0.1. So far H/2 seems to be working fine under normal conditions. But as soon as the request are increasing ( > 800 reg/s) the traffic will stop. Also HTTP 1.1. traffic. Sound like these two problems:

Let us know if we can help to solve these problems.

We haven't added support for 6.1 yet, but we have a pull request to review.

The 6.0.1 release should contain all the latest h2 bug fixes. Please
note that the 6.0 branch is a long term support branch and 6.1 is not
so ignore varnish-modules for now, please be aware of this before
choosing one.

Also please note that there are a few remaining known h2 bugs, but
stability has greatly improved since the 6.0.0 release.
