Squid-dev v3.3.10 pkg 2.2 - squid.pid not being created or updated

pffan

I use squid strictly for it's reverse proxy feature. Before upgrading from squid 2.6, I had first set up a test rig using the squid-dev package and was able to get all the features I needed functioning. But once I upgraded my production box, of course it doesn't work. I can't see the difference between the two configurations but I don't believe a config error is necessarily my problem.

The issue is that I squid will not create nor update it's pid files and possibly others as well. According to the config below, squid should be creating the file at /var/run/squid.pid but it's not there and squid cries 'ERROR: No running copy'.

Here's what I've tried:

Manually creating squid.pid with the pid of the squid process as suggested in http://wiki.squid-cache.org/SquidFaq/TroubleShooting#squid:_ERROR:_no_running_copy though this allows me to update my configuration until I need to restart squid, at which point I must manually update the pid file.
kill -HUP <pid> didn't create nor update squid.pid
Thinking I have a file permission problem, I enabled r/w access for all users on both /var/run and /var/run/squid.pid to see if squid could then create/update the pid file.

I'm out of ideas and running out of time. I should note that the configuration backup I created before starting won't restore and the old version of squid I was using previously is not available from the package lists so I'm really out of luck here.

The config may contain options from my old configuration.
