[squid-users] Upgrade to 3.4.3 and TCP Connections to parent failing more often

Hi

I have recently upgraded our Squid servers from 3.3.11 to 3.4.3 and am
seeing the following error every few minutes in the cache log.

2014/02/17 13:43:02 kid1| TCP connection to wwwproxy02.domain.local/8080 failed

I have 2 servers configured on the LAN which handle connections over a
private WAN and 2 other servers on another WAN connected to the
internet. The first 2 servers use the second pair of servers connected
to the internet as a parent with the following lines in squid.conf:

cache_peer wwwproxy01.domain.local parent 8080 0 no-query no-digest carp
cache_peer wwwproxy02.domain.local parent 8080 0 no-query no-digest carp

With 3.3.11 I occasionally got the error, maybe two or three times daily.

Does anyone have any ideas why this might be occurring on 3.4.3 but
not 3.3.11? I've had a look at debug_options but can't see a section
that screams "debug me" for this particular error. Maybe section 11 or
15?

Many Thanks

Paul
