Cached memory is a mechanism used by Linux to speed up file read and write speed. It cannot be disabled and it would be automatically reclaimed by the system before memory thresholds are triggered. Recycled memory would be what no one is using and what is in use will not be released and will not affect other services.

If the memory utilisation don’t keep increasing, please don’t worry about it.
