One way I did not mention to bypass any allocation issues is to use Separate Processes when Rendering in Poser 7. Poser Pro you also can use Background or Queue Rendering. With that said, if you have a 64 Bit OS, and use Background Rendering you will have more Memory allocated for the Rendering.

Personally, I rarely run into any errors Rendering with Memory so I have little personal experience with it. From other users, I do not think anyone has been able to duplicate an error, so it is really hard to be sure what caused it most of the times.

Some things I do are

 

Save my File before Rendering, confirm all my Render Settings are as I intended, and then Render.
