why frequent floating Ip failovers with keepalived?

we configured a keepalived failover for two load balancers. LB-01 and LB-02 based on your tutorial and the /etc/keepalived/master.sh.

The whole thing works fine. but I notice frequent floating failovers. I increased the interval but it seems to have no effect. The check is the haproxy :

vrrp_script chk_haproxy {
script "pidof haproxy"
interval 3

So to have a failover, either the keepalived service is down or the haproxy pid check fails. In both cases, I do not see in the logs a service problem. Do you have such issues on other setups?
