if it's a timeout problem, the connection will be dropped
always.

what's "long" - more than 15mins?

sure. The timeout is incase a session somehow gets lost and
allows ipvsadm to shed these connections. However the
timeout seems to bight a lot of people. I wonder if it
mightn't be better to have the timeout at something like
24hrs. The ipvsadm table would have to carry dead
connections for 24hrs, but I don't think that would be a big
deal.

Do you think it would be sensible to change the
timeouts?
