Thanx for the tip but my guess is that some reused code for indexing the pages is causing the problem. So I think the solution seems to do fine tuning for garbace collection parameters for HotSpot VM.
I found at http://java.sun.com/docs/hotspot/gc/index.html the document "Tuning Garbage Collection with the 1.3.1 JavaTM Virtual Machine" that may make things clearer. However tips on this task are still appreciated. fred On Tue, 21 May 2002 [EMAIL PROTECTED] wrote: > > The Rete algorithm is memory intensive, you'll recall, but you can > manage memeory usage in several ways.
