When Broker Monitor starts a Broker Server, it internally captures the process ID that the operating system assigns to the server process. Using this ID, Broker Monitor continually monitors the server's run state. If the server exits unexpectedly (that is, it is not stopped in a controlled way through the Broker user interface or the server_config utility), Broker Monitor automatically attempts to restart it.

To avoid the situation where Broker Monitor keeps restarting a Broker Server that is unable to stay up and running, Broker Monitor will not restart a Broker Server that has experienced three unexpected exits within a five minute period.
