These are a Squid process not being able to open /dev/shm UDS sockets.

These ones are the result of /dev/shm UDS sockets not existing.

Check the /dev/shm has write permission for everyone. And that Squid is
fully shutdown and restarted (not just reconfigured). And that no other
Squid process is already running - that includes a previous "squid -z".
