Clean-up of Event Management
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=5. Events older than the specified number of days are automatically purged from the Event Management utility.
