How can we predict memory usage for operations? (To avoid OOM)

I hope this question is not hopelessly naive for the Alfresco community. Using Activiti community version 6.0, it's been easy for test processes that we've created to OOM our service when creating certain processes.

I'd also be intestested in any sizing guidance out there as I'm working on an application which will potentially need to scale to very hign levels of usage. I'm anticipating performance profiling it myself to determine exact sizing requirements, but any information to use as a starting point would be useful.

I did come across these links, which are more about performance and database sizings, and for an older version, but it does have some useful pointers as to potential bottlenecks - which may also be reflected in memory usage. One area mentioned that I know myself can have a big impact is history. If you don't need that it might be worth trying turning it off to see what impact that has.
