"Squid is already running!" errors on restart

[dewey]

I sometimes notice that the proxy isn't responding any more and then I see that the logs are full of "Squid is already running!" errors. Is this something anyone here has experienced before? It might be some race condition on the restarting and I haven't really investigated more so far.
