Hi
We have squid running fine, but every now and then the network connection to
squid goes down.
Then if you try ping the host, it fails.
After the server is restarted, it works again until next time.
I have included a section from cache.log which is when squid stopped
working.
I see near the bottom of the log it says it's shutting down...

Please could someone tell me if they know what is causing this.
Someone has told Squid to restart.
Running "squid -k restart" will do that.
So will sending the process ID the restart signal.
So will passing the CacheMgr control system a requests for the "restart"
object.
A manual restart is the only way I know of that will cause that "Exiting
normally." message.
