Naviagent not responding on unix host

Had two hosts that were not responding to navisphere, "agent is unreachable" or some bable...

on each host there was a /agentID.txt file that the agent reads before re-creating the /etc/log/HostIdFile.txt     The purpose of agentID.txt is to make naviagent bind to a specific IP address on a multi-homed system.  The IP address listed in the file doesn't need to exist on the system, it uses the IP without verification.

I stopped the agent, deleted both HostIdFile.txt and agentID.txt, then started the agent and it now is using the correct IP address in HostIdFile.txt
