I have the same problem but the Ubuntu version is 16 and MySQL 5.7
When I create the daily MySQL backup by mysqldump command the allocated memory by MySQL changed from 15% to 89% and not released.
It causes many problem on the server.
We have about 10 databases which has about 140 tables with many data.
