The events table can grow rapidly.Running the table administration program,
rmstbladm, with the -c option removes old entries. This should be done periodically
using a cron script. See Page 5-44 for details. The data-lifetime attribute in the
attributes table (see Section 10.2.3) determines how old the entries must be before
they are removed.
Events are discussed in detail in Chapter 8 (Event Handling).
