blocked process threshold option allows you to specify the threshold, in seconds, at which blocked process reports are generated. By default, no blocked process reports are produced.
blocked process threshold uses the deadlock monitor background thread to walk through the list of tasks waiting for a time greater than or multiples of the configured threshold. This option is useful when debugging systems with many deadlock situations. However, there is a cost of overhead involved, so it should be used for only short periods of time.
