I don't recall a scenario like this, but I guess it is technically possible.
Just like disk thrashing caused by running one too many applications at
once, I guess a module could have memory allocation behavior that finally
causes the reaper to thrash.
I guess I would turn on live objects in the profiler, sort by cumulative
instances, go away for a bit and see what objects are climbing up to the
top.
If you have assets that are SWFs and those SWFs are running, they might be
creating the garbage.
