I was running squid 3.4 on top of Debian 8 (jessie)
I upgraded to squid 3.5 on top of Debian 9 (stretch)

What I notice by checking cache.log is that it stops for a while on

helperOpenServers: Starting 1/60 'ntlm_auth' processes
2017/10/05 11:36:06 kid1| Starting new ntlmauthenticator helpers...

This was not a usual behaviour on Squid 3.4;

At the moment of the upgrade, I had to adjust various path from
"/squid3" to "/squid" ..

I checked authenticators path and other occurrences in conf file,
everything seems to be ok.

Just for testing purposes, I would try my config on a new clean install,
just to be sure this is not related to the upgrade in some way, and let
you know!
