One of the apparent causes of the Memory Bug is rendering on Default Firefly settings. Apparently Texture Filtering is one of the root causes. Me, I always switch over to Manual Settings and am able to render a scene using 2 Unimesh, One DM background setting with lights, 1 Sixus1 monster, Clothing, morphs and still rarely see the memory bug. In fact my P6 is EVEN MORE STABLE than P5 SR4... I literally forced the memory bug to occur by trying to render a 4 unimesh scene with one of Kawecki's background props, Stonemason's Sci-Fi containers, lights, morphs, and other assorted props and textures. I think the memory bug can be annoying, but there are ways around it. This is just someone that wants what they want, when they want it, and will trash anyone that doesn't agree with them.
