If the above is an exact copy-paste of your cofig file then the syntax
is invalid. Squid-3 may have accepted it but Squid-4 is a bit more
pedantic about correct syntax.

Also please use the "none" keywords instead of "-1/-1" values (note the
absence of whitespaces around those numbers).

How did it stop?

More to the point, why was the above working at all?
 * proxy_auth requires remote helper lookups to authenticate.
 * delay pools cannot perform that type of lookup.

The discussion ends with a reference to more details in another thread.

*If* Alex's guess is correct, then the bug will be fixed in Squid-5. You
can try that cutting-edge code. Whether that is actually your problem or
not, nobody knows.
