[Linux-cluster] Network detect failure



Hi all,
 
I just configured a two node(node01, node02) cluster and the IP resources defined with
 
<ip address="10.1.1.1" monitor_link="1"/>
 
I observed that the server will conduct ping test every 60 seconds.
 
Every day, the active node will get network link detect failure several times.(The time and frequency happen randomly)
Nov 21 14:39:29 node02 clurgmgrd[5841]: <notice> status on ip "10.1.1.1" returned 1 (generic error)
 
When node02 detected failure, it can successfully fail-over to node01.  However, the network link in node01 will also detect failure within several hours.  It will then auto fail-over to node02.  It happens between node01 and node02.  I don't see any link down in /var/log/messages or network switches.
 
Do you have any ideas?
 
Thanks!
