Allocate more memory for the JVM when starting the application/server. As an example, pass the following in to the JVM on startup:
-Xms128m -Xmx256m

By default, the JVM only allocate 64M of memory. You simply need to tell the JVM to allocate more.

Subject	[rules-users] java.lang.OutOfMemoryError: Java heap space on Drools 4.0.4

Hi,

I am getting the following outofmemory error after upgrading from 3.0.x to 4.0.4.
I use to never get this error before.
I don't think this is because of system memory issue.

I have 8 GB RAM Linux Machine with JBOSS Server.

Do anybody have this issue if so what is the resolution.
