Memcached bucket / Expiration
We have a Couchbase cluster with a Memcached bucket.
This bucket is filled by webservers with data coming from DB.
All our cached items have an expiration time of 12 hours.
The strange thing is that the number of cached items continues to increment after several days of use. The RAM used decreases sometimes, but not the number of items.
Plus, even if the RAM used decreases, it continues to grow day by day, and never stabilizes...
I read that MemBase had an "expiry task" running each hour to clean memory from expired items, but here it seems to just increase... do I miss something ?
