I have a VPS running CentOS, and recently its CPU usage goes over 700% two times already. It always turns out to be a process named "updatedb" (as shown in the figure below).
After a quick search, I learned that it is an indexing cron job and I don't think I really need it. But when I try to disable it, I realize that I could not find the "mlocate.cron" in the "/etc/cron.daily" directory, which only has these files inside:
00webalizer logrotate makewhatis.cron rpm spamdyke
As for the "/etc/cron.weekly" directory, it has:
makewhatis.cron
So I don't understand how comes the updatedb process gets started two times in the recent two weeks, and each time it uses so much CPU.
At the time being, I have to kill the process manually from time to time.
