I have got Squid 2.6 STABLE 5 on Debian Etch.
It runs perfectly except for every 10 minutes or so it says
I am running /usr/sbin/squid -N -X to see this error.
I have uninstalled it and reinstalled it using apt-get install squid.
It runs fine for at least two hours after the reinstall and then continues to fall over every 10 minutes.
Thanks in advanced
