That indicates one of several possible things:

1. www1 is handling more connections than www2, or
2. www1 is not closing connections properly

Are the webservers configured in the same way?

What do you see if you do:

ipvsadm -Ln --stats

Also, if you do this:

watch -n1 -- ipvsadm -Ln --rate

[use ctrl-c to exit]

what do you see? I'd surmise that www1 is handling a lot more traffic
than www2.
