prompt The recommendation is to run three separate background engines at different intervals:
prompt .
prompt a. Run a background engine to handle only deferred activities every 5 to 60 minutes.
prompt b. Run a background engine to handle only timed out activities every 1 to 24 hours as needed.
prompt c. Run a background engine to handle only stuck processes once a week to once a month, when the load on the system is low.
prompt .
