Event InformationThis information from some newsgroups may help you:
------------------------------------------------------------------------------
This is a harmless event that can be somewhat safely ignored. This event means that an Agent thought it needed to synchronize its configuration settings with the ELM Server. The Agent sends its configuration data to the ELM Server. The ELM Server attempts to add the Agents configuration objects to its collection, but cannot (most likely because the objects already exist). When this happens, the ELM Server logs this somewhat cryptic message.
If you do see this event, the only to check is your Monitor Items container to see if any Monitor Items have been duplicated. Monitor Items can get duplicated if the ELM Server does not recognize the Agents configuration objects as existing objects in its collection of objects. If you do find a duplicate Monitor Item, delete it. The items will appear identical in all respects, except for their Index GUID, (which can be viewed from the Properties tab of the Monitor Items Properties dialog), and assigned Agents (the duplicate item will likely not be assigned to any Agents, which you can verify by examining the Agents tab on the Monitor Items Properties dialog.
