One possibility is that so many objects get created during rendering that the incremental garbage collector can't keep up. I'm not clear on all the details of GC in SC, but IIRC (very loosely) the GC does partial scans periodically, so that no call into the GC lasts long enough to screw up realtime work. Creating objects in bulk doesn't mean that garbage collection also happens in bulk.

I could be offbase here. I bet some old threads on GC are around in the list archives (probably sc-dev).

i had this problem also with other apps.
could it similar in your case?

I'm not sure I understand exactly what you mean, but I think not. When I render while running top, I can see the SC rsize and vsize increase by 30 meg every time I render.
