statscheck Stats/Server Overload on server?

I Hope somebody can shed some light on this.

I resized my boot partition and resized the /tmp folder. (via the /scripts/securetmp). I also enabled NAT since I'm running a EC2 (AWS) image.

Now since this resize, I'm getting the warning emails:

[statscheck] Stats/Server Overload on [server]

IMPORTANT: Do not ignore this email.
This is cPanel stats runner on [server]!
While processing the log files for user [userid], the cpu has been
maxed out for more than a 6 hour period. The current load/uptime line on the server at the time of
this email is
21:32:43 up 3 days, 21:09, 0 users, load average: 3.10, 3.14, 3.15
You should check the server to see why the load is so high and take
steps to lower the load. If you want stats to continue to run even with a high load; Edit
/var/cpanel/cpanel.config and change extracpus to a number larger then 0 (run
/usr/local/cpanel/startup afterwards to pickup the changes).

If I ssh on the server and do a:

ps -aux | grep [user]

I see a few processes for the [user]. When i kill the process, the stats for the next user are run (hanging??) and its starts again. So apparently for some reason the /usr/local/cpanel/bin/logrunner can't do what it needs to do.

Anybody got a glue ?

By memory it looks fine. Also the log files being processed are pretty simple websites without a lot of traffic.

Hello :)

This stems from the following setting found under the "Stats and Logs" tab within "WHM >> Server Configuration >> Tweak Settings":

"Extra CPUs for server load"

The number entered here is the load average above the number of CPUs at which cpuwatch, cpanellogd, backups, and CPU stats consider the system to be in a critical load state. For example, a server with 4 physical CPUs and a value of 2 in this field will be considered “critical” in these cases once the load reaches 6.

If the server load is only hovering between 3 and 4, you may want to consider slightly increasing the value for "Extra CPUs for server load".

Thank you.

Yes, "1" or "2" should be suitable depending on the number of CPUs your server uses.

Thank you.
