More solutions to problems seen with adding the "worker" setting. To fix this "2012/09/18 10:05:20 kid5| commBind: Cannot bind socket FD 12 to [::]: (13) Permission denied" 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.

... 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.
