I can confirm that the problem still exists with 2.6.14.2. I did not
get a reply the last time I reported the configurations, so I'm resending.
Our system uses keepalived to manage web, ssh, ftp, telnet, and rsync
connections. The web connection is by far the heaviest, with about
300 active connections at the quietest period, going up to well over
a thousand at peak times. We use direct routing, using private IP
addresses (xxx.local, 10.2.xxx). First, here is the result of
ipvsadm on a 2.4 system at the moment:
IP Virtual Server version 1.0.12 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP publ.mcc.ac.uk:ssh wlc
-> pascal.local:ssh Route 8 1 0
-> euclid.local:ssh Route 8 1 1
TCP publ.mcc.ac.uk:telnet wlc
-> pascal.local:telnet Route 8 0 0
-> euclid.local:telnet Route 8 0 0
TCP publ.mcc.ac.uk:ftp wlc persistent 50
-> boole.local:ftp Route 8 2 51
TCP farm.mcc.ac.uk:www wlc
-> zethos.local:www Route 16 79 199
-> cauchy.local:www Route 8 41 112
-> pliny.local:www Route 8 40 116
-> thales.local:www Route 8 40 119
-> kepler.local:www Route 8 41 109
-> euler.local:www Route 8 42 96

TCP jfarm.mc.man.ac.uk:www wlc
TCP farm.mcc.ac.uk:rsync wlc
-> briseis.local:rsync Route 8 0 0
Then, here is ipvsadm-save:
-A -t publ.mcc.ac.uk:ssh -s wlc
-a -t publ.mcc.ac.uk:ssh -r pascal.local:ssh -g -w 8
-a -t publ.mcc.ac.uk:ssh -r euclid.local:ssh -g -w 8

I would be grateful for any further help with this problem.
