A squid box was configured child and can't send to outside.
(BSD/OS 3.0, squid 1.2.beta22, --enable-snmp and --enable-digest)

ISP1 --- Parent squid1 ---\
                           ----- child squid (This box)
ISP2 --- Parent squid2 ---/

All request will send to parents by never_direct.

acl local-ips dst 10.0.0.0/255.0.0.0 133.122.0.0/255.255.0.0 133.210.0.0/255.255.0.0 133.211.0.0/255.255.0.0 192.168.0.0/255.255.0.0
acl local-domains dstdomain ncl.omron.co.jp
acl all src 0.0.0.0/0.0.0.0
never_direct deny local-ips
never_direct deny local-domains
never_direct allow all

Parents are alive very well, but child squid logs these messages.
From cliend side, users think proxy is down.
beta21 did not.

I think beta22 parents judgment algorithm will be broken.
Or I should use dead_peer_timeout etc?
