Updating Varnish to latest version issue

[Dimitris Magnis]

Hello all,

I've just updated my (Centos 7.3) varnish to the latest stable version from
4.1.4 to 4.1.5 which resulted in the following:

Any help will be greatly appreciated!

Thanks in advance

PS. I've never had any similar problem with the previous version (4.1.4)
