[Linux-HA] Load balancing fails

Dear Linux-HA users,

I want to load balance two apache web servers through two load balancer 
nodes with heartbeat on them. I followed a few guides, but cannot get it 
working without the cluster failing after 15 minutes. After some time 
the cluster/virtual ip is down, but after one hour it is up again, and 
so on..... Here is some information: My system runs on Centos 5 and runs 
as guest under vmware server 2 (rc1), these versions are installed: 
heartbeat-stonith-2.1.3-3.el5.centos, heartbeat-pils-2.1.3-3.el5.centos, 
heartbeat-gui-2.1.3-3.el5.centos, 
heartbeat-ldirectord-2.1.3-3.el5.centos, heartbeat-2.1.3-3.el5.centos, 
heartbeat-devel-2.1.3-3.el5.centos. The config-files are included in the 
mail. The ha-debug log file gives these errors:

heartbeat[28951]: 2008/07/24_11:14:30 WARN: Late heartbeat: Node loadi: 
interval 5320 ms

heartbeat[28951]: 2008/07/24_11:14:45 WARN: Late heartbeat: Node loadi:

heartbeat[28951]: 2008/07/24_11:15:17 WARN: Late heartbeat: Node loadi: 
interval 5250 ms

heartbeat[28951]: 2008/07/24_11:15:22 WARN: Late heartbeat: Node loadi: 
interval 5260 ms


Has anyone had the same problem or does anyone know how to overcome this 
problem? Thank you in advance!!! Regards,

Ralf Bardoel
