Major Description
This is probably due to bucket deletion because ep-engine is probably still deleting the kv tables and can not process any new memcached command during the cleanup.
The right behavior would be that "create-bucket" api should fail with error "memcached is still busy deleting the previous bucket"
This behavior happens 100% during rebalance/cluster tests which load lot of items in memcached.
