> Hi everyone,
> I've wrote that rule:
> rule "COMPTEUR"
> duration 10000
> when
> 	$alarme : Alarm ();
> then
> 	$alarme.increment();
> 	update($alarme);
> end
> Using JProfile, I've noticed that PropagationContextImpl was constantly growing
> in the heap. Then, I looked the scheduled activations and saw that some
> scheduledExecutionTime was expired. So, I wrote this code to purge the expired
> activations:
> Activation[] activations = session.getAgenda().getScheduledActivations();
> long now = (new Date()).getTime();
> for(int i=0;i<activations.length;i++){
> 	if( now >
> ((org.drools.common.ScheduledAgendaItem)activations[i]).scheduledExecutionTime()){
> 		activations[i].remove();
> 	}
> }
> Now, the heap isn't growing anymore but what are the consequences of doing
> something like that? So far, there are no noticeable regression on my
> application.
> Thanks for your help.
