In 3.1.6 with --disable-ipv6 the detection is disabled and the result
fixed at off. The core of the code may still pass around IPv6 addresses
from raw URLs or config settings etc.
It looks like this is another spot of the code not being selective of its
socket addresses.

I'm going to need some system and transaction details to understand this
one.

 What is the squid.conf settings please?
 What does netstat say about the Squid ports?
  a trace immediately after one such failed transaction showing the port
details which failed would be great (probably a random TCP link in
TIME_WAIT state).

 What URL was being attempted which fails?
 What does that domain name resolve to from the squid box? (both AAAA and
A)
