Thanks,

that is very interesting,
the ownership of swap.state on all servers are squid,
because it is pipe the echo output so it shouldn't change
the permission.

however was wondering if clearing swap.state is the way of
clearing cache !!!!

I was checking the squid that comes with Centos,
it does not have any flush option, probably flush is a
bad idea ?


sudo ls -la /var/spool/squid/cache/swap.state
-rw-r----- 1 squid squid 5097456 Oct 23 11:44 /var/spool/squid/cache/swap.state

ps -ef | grep -i squid

Hi

we are using SQUID 2.6.STABLE13

we usually restarting squid by flushing it
service squid restart
service squid flush

flush)
        $0 stop
        sleep 2
        echo -n 'Flushing squid cache: '

        echo "" > /var/spool/squid/cache/swap.state

This line isn't flushing the cache and its probably creating a root-owned
swap.state file thats causing your problem.
