        I have one thing to add: It is probably related to using
very different weights. On one virtual server I use weights of 100 and 133
just to reflect the real servers' CPU power, and this one seems to be OK.
On other virtual server I use weigths of 1, 1, 100, and 10000 to make
one particular real server to be used all the time, provided that it is
alive. On this virtual server I get "connection refused" (port unreachable)
when the main real server goes down.

        The example I have posted before uses weights of 100 and 1000,
and it also does not work with these weights. With both weights set to
1000 it works as expected.
