[rules-users] Large Rule base failing? StackOverlowError

[Christie, Blair]

My apologies for not being more specific.
The version of drools is 4.07 and the size is of the serialized file. 
It is 2megs. 
We do not currently have about 200 rules. 

Cheers,
Blair

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? :)

As the email says it seems some more modern JVMs cope better, and the 
work to write a custom marshaller is quite a lot so it's been a lower 
priority for now, unless someone from the community takes this on.
