What version of Drools?

You have 2 million rules? Just to be clear, was it working with 1.9 
million rules? heh I'm intigued on what sort of app you are doing, could 
you do a write up? I'm sure people would love to know about people using 
a really large number of rules.

The limitation you reaching is a limitation of the standard 
serialisation algorithm of the JDK, we would have to create a custom 
marshaller to improve this further, which we may do in the future. 
Unless someone from the community wants to do this? :)
