Comment 1 Ingvar Hagelund 2017-08-04 08:56:07 UTC
This is a simple race between the varnish daemons and systemd. systemd is not patient enough waiting for the daemon to open its pidfile, and gives up.

Workaround: Add 

ExecStartPost=/bin/sleep 0.5

to the varnish*.service files and it should work.


I'll try to figure out how to deal with this most correctly.

Comment 2 Ingvar Hagelund 2017-08-04 09:47:16 UTC
Reproduced with newer versions of varnish (5.1.3) on epel7.

Seems this is not a problem with newer versions of systemd. Fedora 25 and 26 does not have this problem.

So this means that this is a problem with systemd, not with varnish. I'll leave it with the workaround, and add that to the next update of varnish for epel7.
