Simon,

   The system in on 2.6.18 kernel.

   Well, it is not quite true that I run the sync daemon on two machines.  It 
is running on 4 machines.  I have 4 machines, 2 of them are in a group.  I want 
to separate a pair of each because they are handling different type of traffic. 
 So I want one pair handle their respective load sharing traffic.  I notice 
that if I stop the other two machines running sync daemon, the bogus message 
stopped.  I tried with syncid option, but I still see the bogus message in the 
klog.  It comes out about every 5 sec.



Hei Wah
