Your probably not out of memory. i get that error after poser tries to load an obj file that is either damaged or not in the right directory. If you get a message beforehand about not being able to find a particular obj file then this is your problem. I seriously doubt it's memory as I've loaded files that were like 50+meg before and not had an issue with it (took a long time to load though). I seriously doubt clothes would overload your memory.
