Sorry for my bad english, I'm italian.
I have squid 2.4STABLE6 in a debian linux system.
I use this proxy server to give internet connection to 700 clients in
a local network.
I always have this kind of errors in my syslog:

As you see I think it's a DNs problem.
The strange thing is that if I reboot squid for a while I have any
problem.
If I connect directly without proxy I have any problem too.
DNS they works well.
How can I do to resolve this really serious problem?
Thnak you.
