[users@httpd] Crash in http/2
Hello!
Using 2.4.17.
There seem to be an issue with http/2:
I have these in the vhost error log:
[Tue Oct 20 12:00:35.797584 2015] [http2:warn] [pid 21608:tid

Check the timestamps. It seems after the warning is logged, a few
minutes later the process crashes.

Oh, the client seem to be a Firefox 41 from that IP:
Mozilla/5.0 (Windows NT 6.1; rv:41.0) Gecko/20100101 Firefox/41.0

This looks like a bug that was fixed shortly after the 2.4.17 release.
When the client resets a HTTP/2 stream (request) before the server
has started submitting a response, mod_http2 trips and this may
lead to a crash later, as you observed.
See http://svn.apache.org/viewvc?view=revision&revision=r1708124
In case you build your server yourself, I can setup a 2.4.x branch
with changes applied...
