Do this
#chown squid -R .../var/run/squid/
There is something very strange going on with your system permissions.
Firstly a kernel SHM device (used by the kernel itself) is not operating
properly, then your Squid is installed without ownership and read/write
of its own directories.

Unfortunately there is now another problem a rolling failure of the children
process by the looks of it.

... now the UNIX sockets are not relaying packets or the worker
processes are not responding fast enough. These sockets are another
kernel internal messaging system, so they shodul be working, but with
the SHM problem you had I'm not going to assume that.
One possible cause is that you have very large cache_dir configured and
the workers are busy loading those into memory with all the slow disk
I/O and RAM allocations that entails.
Another is that the SHM device is still not working properly, even with
tmpfs space allocated for its socket handles.

After adding the shm fix, I now get the flowing as seen in the log below, it
appears to not specify a port number.
Still struggling to configure with multiple workers.

SHM FIX::
Just add the following line to your /etc/fstab file:
shm /dev/shm tmpfs nodev,nosuid,noexec 0 0
After that use (as root):
# mount shm

I just added "workers 4" to my working configuration and I get an shm_open error. I
assume it is trying to write to the root directory "/squid-squid-page-pool.shm" as the
user squid which will fail.
How do I redirect this?
Thanks Mike
