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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1789343 Title: mysqldump in MySQL 5.7 running on Ubuntu 18.04 does not release memory To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1789343/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
