CPU-Load is high

Hi there,
since some days I get a high CPU-load with server crashes, the memory load is normal/low.
When I call htop I see every some minutes that du -ks /home/userdir is called by root. This is the moment, that the CPU-load is high. But I don't find a solution where it is called.

In the crontabs there I can't find an entry and under /var/spool/cron I also can't find anything.

What I have installed in WHM is called Recource Monitor. But there are all user-dirs deactivated. So, can anyone give me a tip where to look?

Regards
Thorsten

 

root@server [~]# ps aux | grep du
root 4904 89.7 0.0 4696 1364 ? R 20:40 0:09 du -ks /home/userdir
root 5126 0.0 0.0 103332 888 pts/2 S+ 20:41 0:00 grep du
root 19381 3.1 0.4 141200 38828 pts/1 S+ 20:06 1:05 grep -r -i du -ks ./

Hm, I think that helps not so many, because that is what I know. What I have seen is, that "du -ks /home/userdir' is called in minutes and in one userdir it has to stay longer, because there are 120 GB.
In the other cron.* dirs I have looked but not found any suspicouse.

 

Yeah Haaaa, I got it:

root@srv [/]# grep -r -i 'du -ks' ./
./usr/lib/monitorix/du.pm: $line = `du -ks "$str"`; # in KB

in monitorix.conf:
<graph_enable>
system = y
kern = y
proc = y
hptemp = n
lmsens = n
nvidia = n
disk = n
fs = y
zfs = n
du = y
net = y

Set DU = to "N" --- thats it.

Thanks for your help! And good night

Thorsten
