[rules-users] Memory-Problemwith instance of "ReteooStatefulSession"

[Wolfgang Laun]

Please provide detailed information about
   - the number of your rules
   - a statistic of the complexity of your rules (r rules with p
patterns, p = 1,...)
   - a statistic of the facts (f facts of class C, with one C object's
size being s)
