The heartbeat monitoring agent will either not start, or stop (crash) shortly after it was started. You will see an "Application Error" event log entry in the Application event log indicating that the eventsentry_hb_svc.exe faulted.

This problem appears when you have one or more duplicate computers in your configuration.

Check your entire configuration and make sure that there is no computer and/or IP address that appears more than once. A computer and/or IP address should not appear more than once even when located in different groups. You will only have to check groups that are heartbeat-enabled groups.

The management application does, unfortunately, not enforce this limitation in version 2.60.
