[squid-users] Parent TCP connection failed

Hello,

I'm running two frontends instances on ports 3128 and 3129, and two
backend instances on ports 4001 and 4002 on the same box, and
loadbalancing between parents using carp.
cache_peer localhost parent 4001 0 carp name=backend-1
cache_peer localhost parent 4002 0 carp name=backend-2

squid -v
Squid Cache: Version 3.1.15
configure options: '--enable-async-io' '--enable-linux-netfilter'
'--enable-storeio=ufs,aufs' '--exec-prefix=/usr' '--bindir=/usr/sbin'
'--libexecdir=/usr/lib/squid' '--enable-carp' '--enable-cache-digests'
'--enable-removal-policies=lru,heap' --with-squid=/opt/squid-3.1.15
--enable-ltdl-convenience

After successfully starting all instances I see on the frontends
cache.log:
2011/10/07 16:10:56| TCP connection to localhost/4001 failed

Because only backends are caching, not connecting to then all traffic
from frontends is forwarded to the origin servers, making the storages
useless.

Any suggestion will be appreciated!
