bneradt opened a new issue #7915:
URL: https://github.com/apache/trafficserver/issues/7915
I've noticed that CI has started having intermittent failures with the
h2spec.test.py test. I reproduced it locally, running the test 20 times, and
noticing that it would fail consistently within a few runs. I did a git bisect
and here's the results:
```

Those results seem to indicate that this PR has made the h2spec test to pass
inconsistently:
https://github.com/apache/trafficserver/pull/7809
For those trying to reproduce these results:
* Docker image: `controller.trafficserver.org/ats/centos:8`
* `./configure --prefix /var/tmp/build --with-openssl=/opt/openssl-quic
--enable-experimental-plugins --enable-example-plugins --enable-werror
--enable-debug --enable-wccp`
* `./autest.sh --sandbox /tmp/sb_master --ats-bin /var/tmp/build/bin/
--clean=none -f h2spec`
