Zabbix_agentd is not running but really is..

Hi,

I have 3 nodes that are part of a larger cluster. One is a master image 2 are clones , the clones are binary identical to the master.

On the master and on 1 node the I see

Number of running processes zabbix-agentd 12 Apr 2012 10:41:18 1
.
Version of zabbix_agent(d) running 12 Apr 2012 15:20:56 1.4.7

on the other node I get

Number of running processes zabbix-agentd 12 Apr 2012 10:41:18 0
.
Version of zabbix_agent(d) running 12 Apr 2012 15:20:56 1.4.7

I get all the stats from the second node and all data and triggers are working correctly but for some reason the agent is not known. These are RHEL 5.4 systems but I also see this with 2 Centos 6.2 systems, one works the other works but reports the agent as down when it is not.

Any thoughts?
