who is this nobody?

My server is showing abnormal load. When I checked with WHM/Cpanel -> System status the Red button is coming with Server load status row and PHP's system uptime function showsing following details:

load average: 2.05


After looking into the System Health -> Show Current CPU Usage . I found following entries which are consuming CPU resources:

16311 nobody 0 97.2 72.9 /usr/local/apache/bin/httpd-DSSL
16214 nobody 0 97.2 72.9 /usr/local/apache/bin/httpd-DSSL
17045 root 0 1.3 0.1 top -n 2 -b -c
131 root 0 0.5 0.0 kjournald

I was wondering what does first 2 entries means which is owned by nobody?

And what is the top -n 2 -b -c & kjournald commands do which are owned by Root?

After few minutes of investigation when the Load remains save, I killed all the nobody operations. I need to kill the above 2 operation 2 times to put the server load in normal. I don't know whether its right to kill such operation or not. Can you suggest?

My Server is running with Red hat linux 7.3 with WHM/cpanel5.

Thanks.
