Hey guys,
                I have two freshly installed directors, running Ultramonkey
on Debian Sarge with a 2.6.18.1 kernel - on very overspec'd hardware.  All
is well except, I have noticed when enabling connection synchronisation both
machines slowly rise to a load average of 1.00 without any apparent cause.
These machines arent in production, and are idling in every other way -
infact there isnt even any state information to multicast.  If I disable the
connection synchronisation daemon, and reboot.  They stay around 0.00~ as
expected.   Is this load obscurity normal ? or have I barfed something.
 
The two directors do their multicasting via cross-over on eth1.  Other
config info below:
 
director01:~# w
 17:34:04 up 58 min,  2 users,  load average: 1.00, 1.00, 1.00

director01:~# cat /boot/config-2.6.18-1-686 |grep IP_VS
CONFIG_IP_VS=m
