Every few hours some processes killing server

Hi,
on one of my servers last few days I have very big problem (after cPanel upgrade to last stable version) and after I added third HDD (ssd) for mysql (mounted to /var/lib/mysql), every few hours cpanel start some stupid processes like quotacheck (this server is only for me and I don`t need quotas) and

and

m5sum

and few others, after it start load on my server go up up up and sometimes over 100...

What to do???

What of this I can disable and how???

I already edited crontab and set backup to do at 5AM...

For me look like something is not good with last build (WHM 11.30.6 (build 3)) because on other server I have WHM 11.30.4 (build 6) and all working fine....

Thanks.

 

ex3 for new HD...
