[squid-users] Load Balancing Problem

Hi,

I need help for load balancing my Squid with two ADSL links. I have try to
run additional two Squid parent instances on the same machine but with
different IPs binded by using tcp_outgoing_address. It works, but
sometimes it generate some error on main Squid like this and make the
speed going slower than using just one Squid with single ADSL link.

2007/09/20 00:00:42| TCP connection to 192.168.1.254/3128 failed

Here is my topology.

Main -(round-robin)> Parent1/Parent2 -(tcp_outgoing_address)> ISP1/ISP2

Any idea about this error ?

Best regards,
