This can't be your running configuration. With this configuration peers
won't be used at all as you are forcing all requests going direct via
always_direct. With this configuration access.log MUST say
DIRECT/xx.xx.xx.xx or cache hits only, never TIMEOUT_* or any peering
related tags as peers are excplicitly forbidden to be used.

Again, are you really really sure you are looking into the correct
squid.conf file on your Squid2 and Squid3 proxies? Perhaps you have more
than one copy..

Nothing else?

You should focus on what Squid2 and Squid3 says when they forward the
requests to your Squid1.

So how does they then end up in your two carp parents? You do not have any
clients using these from what I understand.

How did that request end up at carp1.mydomain.com, and what did it say
about how it forwarded the reqeust?
