Re: [rules-users] Large Rule base failing? StackOverlowError
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

We are having a problem reading in large serialized files. We get a

Is there a way to overcome this without increasing the stack size?
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? :)
