Thanks for your reply Andrew....
Yea it should be ,,, My heartbeat link is via a cross over cables directly
connected... How about increasing the 'keepalive' time or 'deadtime'
again....

IN my ha.cf.deadtime' is 60sec, warntime is 50sec...
In my pingd resource i have given dampen as 60sec, monitor interval as
65sec, ie, greater than dead time in ha.cf... ohhh.... did i missed it... My
dead time in ha.cf is same as dampen in pingd... Could it be the issue...
However it is not supposed to give a failover when I restart my network,,
naaa?


With lots of thanks and regards,
