I'm not (so far) seeing any other processes using any significant amount of RAM, apart from MySQL. But that seems fairly static at 1.7%.
That suggests it may be a single thing that happens that causes something to eat memory all of a sudden. I'm afraid you'll just have to keep waiting in this case :)
Part of the point of this exercise is simply to see if memory usage stays constant over time or if it suddenly gets used exponentially or linearly which might help you after it has gone wrong again.
