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.

... 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.
