I recently installed kubuntu 16.04 on my Dell studio xps 1640 that has 8GB of Memory installed. Everything is working fine but Something is really bothering me. After a fresh boot up, when i check the system resources,
mysqld occupies about
150~200MB of RAM and a bunch of
akonadi services are running(contacts, birthday,mail*, sendalter & ...) and i really don't need and use any of these services and it's a waste of Memory. But the serious problem is with mysqld, after a while(3-4 hours) mysqld occupies about
800MB~1GB of RAM and it won't release that until i reboot the system. I should mention that i don't have any running databases and don't use mysql at all! So only ubuntu is using that.
So my Question is that:
First, how can i disable (remove) the unwanted akonadi services and don't let them to autostart and run at all (I disabled akonadiserver but didn't help). The only service that I'm using from akonadi is krunner and i really don't need the kMail, Calendar and ... .
Second, why mysqld is taking this amount of memory(although i guess its related to the akonadi issue mentioned above because the Parent of mysqld process is akonadiserver) and how can i prevent it. because my work is related to RAM usage and i really need the Memory so i can't let that unwanted services use this amount of resource.
I really appreciate it if you would help me to fix this problem. Thanks in advance for your kind help.
