That's likely the best way but it won't recreate the original environment and that may be the problem. Imagine that the oldest file accounted for 30% of the cache space. Well, purge will still purge that file and fall far below the low water mark. Then it will just sit there until the space gets used up. Sounds like a rational explanation?
