this mysteriously happens sometimes. There's always some
rational explanation after the fact, but it isn't obvious at
the time. It happens because there are 3 nodes involved in
making a 2 node connection. Things that are taken for
granted in a 2 node connection don't always work in a 3 way
connection.
You may have to feret it out yourself. Possible things are
o someone has to do DNS and it's failing
o you have identd on the realserver (turn it off)
o there's some routing wierdness and icmp's etc are having
to figure out the right path.

if it was LVS-Tun, then there is the MTU problem, but LVS-DR
doesn't cause these problems.
Are the users having the problem all on one network -
are they behind "wierd hardware" (see the HOWTO).
What's in common with the one's having the problem?
