Hyperion Planning : An Error Occurred. (Tomcat)

After reinstalling Hyperion Planning 4.0.2, I met the most funky error message ever generated.  It says : "An Error Occurred.".  That's it..  No other description or details.  At first it only happened when I opened a large form, but soon after any other form generated the same error message.  I tried restarting the planning application server (through Tomcat) and it got it working, but soon it generated the same error message.

The problem is located on the JVM.  You might want to increase the -Xms & Xmx.  

Edit : \Hyperion\HyperionPlanning\Deployment\Tomcat\4.1.30\startup.bat using your text editor.

Update the following line :

set JAVA_OPTS = -server


set JAVA_OPTS=-server -Xms512m -Xmx1024m

You can change the 512m / 1024m as you see fit.  A great description of Xms & Xmx and it's best size for your system could be found here.
