[squid-users] TCP connection to failed

Hi all,

We're experiencing this strange issue with squid on NetBSD. During
busy hours we're seeing repeated error messages in squid's cache.log:

Failed to select source for 'http://...'
TCP connection to x.x.x.x/3128 failed
TCP connection to x.x.x.x/3128 failed
TCP connection to x.x.x.x/3128 failed
...

x.x.x.x is the upstream proxy as configured in squid.conf: cache_peer
x.x.x.x parent 3128 0 no-query default name=x.x.x.x:3128

As a result, on client machine a user would see "Unable to forward
this request at this time" message on their browser. This doesn't
occur when network is less busy and we're seeing the same issue with
different upstream proxies. Is there anything we could tweak on
squid/OS to overcome this or parent proxies are the one to blame here?
Any advice would be great.

Thanks.
Tuan
