Re: [rules-users] Out of Memory Exception While Running Rule

I have run several times this number of rules with Drools. Mark is right that adding Permgen space will help, but you can also reduce the size of your identifiers to use less Permgen memory. The harder issue to handle is running out of heap memory if you run a few thousand more rules: at some point the time required for compiling rules and inserting objects goes up dramatically due to thrashing. -- View this message in context: http://drools.46999.n3.nabble.com/Out-of-Memory-Exception-While-Running-R...
