Alfresco Memory Tuning

I've roamed around the forums and the wiki for information on memory tuning of Alfresco, but didn't see anything of a comprehensive nature so I thought I would ask here about this. Our Alfresco instance (Alfresco 3c Community) is about 5 GB in size (a lot of mid-size documents and some larger 100-250MB binaries). We have about 10 concurrent users and perhaps 50-60 total users. We are running on RHES with JBoss 4.2.3 and JDK 1.5_u17. We seem to be running out of heap on a regular basis. We're trying to figure out why.

We currently have 1 GB of RAM in the startup script for the heap. Is there a memory tuning guide (I know about the quick wiki page) or any advice that you have for what we can do to figure out why we keep running out of memory? The error we get is "outofmemory". Our JBoss config is essentially out-of-the-box except for the heap size.

Any help would be great - or let me know what additional info I should post here.
