[Bug 1576930] [NEW] Excessive consumption RAM of mysqld daemon in Kubuntu 16.04

[Launchpad Bug Tracker]

In the last days using Kubuntu 16.04 I've noticed that after a while of
use, RAM consumption of mysqld daemon rises above 800 MB, even
surpassing Firefox, as you can see in the attached images.

Initially, when system is just booted, RAM consumption of mysqld daemon it remains approximately 135-140 MB, but I have seen how after a while, in a matter of a few minutes, without touching anything, consumption rises progressively to around 830 MB.
In the second image you can see that mysqld daemon is related to Akonadi, which at the same time has a lot of threads running. It is possible that the problem is in managing Akonadi processes, but it is clear that consumption of mysqld daemon is not normal, and that there must be a problem, either MySQL or Akonadi, causing this situation.

I tried replacing MySQL with MariaDB, but will not let me uninstall
MySQL components without also uninstall a lot of applications as
dependencies (like Akonadi, Amarok, Kontact, KAdressBook ...). What I
can do, even as an interim solution?
