I've had simular problems in my work- especially if there's alot of texture in the scene. If you go to render settings and switch to the manual screen, You'll see a glide bar for the texture sampling size- it's usually set at 1024. set it as low as it will go- usually about 512. Next, go to the bucket size directly below it. Normally this is set at 64. Knock ten points off of it- set it 54. The render may be a little slower, but Poser won't yell at you as much. Another option that I used alot on my Red Sonja series, is breaking the render down into smaller files and then recombining them. Example- say you're doing an indoor scene. Take the ceiling, wall and floor, maybe one figure and render that first. Then re-import that as the background for the next couple of figures. Make sure you're lighting stays the same- you might write down the settings so you can re-create it. I don't know how old you are, but if you have access, take a look at Red Sonja and the Witch of Lankar:Part 11. This was done this way- it took five renders to pull it off. here's the adress; http://www.renderosity.com/viewed.ez?galleryid=1040484&Start=1&Artist=mdbruffy&ByArtist=Yes Hope this helps.
