From: Barry K <barry.knapp(a)railinc.com&gt; Subject: [rules-users] Patterns in Memory To: rules-users(a)lists.jboss.org Date: Tuesday, March 3, 2009, 10:47 AM Do the number of patterns in memory stabilize after the rulebase is created or can transactions increase the number of patterns? Reason I ask is I have 2 servers with the same rules loaded and one shows 3000 patterns in memory but the other only shows 2300.

The Patterns object, I expect is just the various condition and action nodes of each rule in the rulebase.

Sorry I do not have code to provide for the memory footprint, we use I3 to get a snapshot of all java objects in memory from each server.
