I have net.inet6.ip6.v6only = 1 in my system. But I'm sure that I have 
not manually set this parameter.

That being said, both squid ans mysql worked fine with -6, -7 and don't 
with -8 with default configuration.

I don't know if with -6 and -7 these daemons listen on both IPv4 and 
IPv6, but they listen at least on IPv4.
