OutOfMemoryError: Java heap space

[Jacopo Cappellato]

Hi all,

I have noticed a "OutOfMemoryError: Java heap space" error happening  
quite frequently on some production ecommerce site running on OFBiz.
Anybody else have noticed this error on a recently updated server?
This error may be related (but not sure) to the upgrade to Tomcat 6...  
maybe there is something wrong in the way we create the embedded  
instance of Tomcat.

Thanks,

Jacopo
