[rules-users] Patterns in Memory

[Greg Barton]

Do you mean org.drools.rule.Pattern?  If so, it is created when the rules are compiled, and with identical rulesets I'd expect you should have the same number on each server.  Edson or Mark would know if that's not the case.

Are your rules ever recompiled between runs?  

Can you provide the code that takes the snapshot?
