#4457 [HHQ-4254] All agent metrics are unscheduled in HA environme

[Hyperic Team]

http://jira.hyperic.com/browse/HHQ-4254
To reproduce:

Configure 2 node HA environment


Add one or more agents to the inventory


After few hours all agent schedule gets wiped out.

Here's sequence of events reconstructed from agent/server logs.

- Server reports that agent is sending data for non-existing entity, following message is repeated for all resources under an agent:


2010-08-27 05:54:40,931 ERROR [Thread-6870] [org.hyperic.hq.measurement.server.session.SRNManagerImpl@201] Agent's reporting for non-existing entity: 3:10108

- Few seconds later agent gets unschedule measurement command from server for all of its measurements:
