I would not rely as it is flushing least recently used items very
frequently even if the cache is very small. I have kind of same
problem and have posted question on this forum about that.  "MemCache
expiring around once a day" and yes it was wrong about once a day
instead any time & very frequently.

Thanks,
Rahul
