I guess you fill up 1MB rather quickly, so the item in question is never repositioned in LRU queue, and eventually popped off despite the fact of being accessed frequently.
That's almost certainly it. In general, if you're cycling through your entire cache in under 1 minute, it's a sign that either (a) your cache is WAY too small, or (b) you're doing a stress test that isn't anything close to representative of real-world conditions. (Or both, in this case.)
