Cleanup of the Event Management Utility
To avoid possible performance issues resulting from an accumulation of a large number of event records in the Event Management utility, add the following site-wide property to wt.properties: com.ptc.core.task.purgeTasksOlderThanDays= <integer>. Events older than the specified integer (number of days) are automatically purged.
For more information on the Event Management utility, refer to Conflict Management.
