I am using linux heartbeat to keep ldirectord running on my webservers.

My logs show heartbeat WARN: 1 lost packet(s) every couple of minutes, and I'm having trouble figuring out why.

I have tried altering DEADTIME and WARNTIME in /etc/ha.d/ha.cf, but these appear to address late packets, not lost packets.

netstat -ai reports no errors on my interfaces

Any idea what is causing these warnings, and how I can address them?

try looking at congestion on the switch, icmp has less priority then ip, heartbeat is icmp.

use a dedicated switch for inter server communication.

Great suggestion. These are virtual machines, so I'm not SURE that this will make a difference, but I will try setting up a dedicated virtual switch/vlan for heartbeat. Thanks. –  Brent Jul 23 '09 at 21:49
