[squid-users] When does squid show "TCP connection to A.A.A.A/8080 failed" ?

Hi, squid users

I found many "TCP connection to P.P.P.P/8080 failed" messages in cache.log.
When squid show "TCP connection to P.P.P.P/8080 failed", which pattern is TCP connection to
parent proxy ?

1)
C.C.C.C --> P.P.P.P:8080 Syn
C.C.C.C --> P.P.P.P:8080 Syn
C.C.C.C --> P.P.P.P:8080 Syn
...
Timeout!(peer_connect_timeout)

2)
C.C.C.C --> P.P.P.P:8080 Syn
P.P.P.P:8080 --> C.C.C.C Syn Ack
C.C.C.C --> P.P.P.P:8080 Ack
P.P.P.P:8080 --> C.C.C.C Rst

3)
P.P.P.P:8080 --> C.C.C.C Syn Ack
C.C.C.C --> P.P.P.P:8080 Rst

C.C.C.C is child squid IP.
P.P.P.P is parent squid IP.

Thanks
Tomi
