First step is to create the following file, it should disable cpanellogd:
touch /etc/cpanellogddisable
Now kill all cpanel logd process by finding the PIDs
ps aux | grep cpanellogd kill -9 PID#
Above please replace PID# with the PID number for the process running for cpanellogd.
Additionally, to ensure cPanel restart does not start cpanellogd (I tested and even with the /etc/cpanellogddisable file, cPanel restart still tries to restart the process), you would want to move the following files:
mv /usr/local/cpanel/cpanellogd /usr/local/cpanel/cpanellogd.bak mv /usr/local/cpanel/libexec/cpanellogd /usr/local/cpanel/libexec/cpanellogd.bak
After doing the above steps, cpanellogd should no longer run on your machine.
cpanellogd is important process, read about it before disabling http://forums.cpanel.net/f5/how-kill-cpanellogd-73439.html#post341757
