Rayson,
thanks for you quickly answer.  The reason I am looking a good value to sue with this parameter is because yesterday we came into the problem the scheduler just stop to dispatch jobs having available resources.  The messages file reported lines like this one:

03/25/2009 17:02:04|event_|cerebro|E|no event client known with id 1 to process acknowledgements
03/25/2009 17:02:04|event_|cerebro|E|no event client known with id 1 to modify

so, it was required to restart the qmaster which solved the problem.
