Hello,<br />
<br />
while the system is running and I am logged on, I am getting this message almost every ~30 seconds:<br />

[<a href="mailto:root@db1">root@db1</a> ~]# uptime<br />
21:58:40 up 7:56, 4 users, load average: 11.77, 11.57, 11.53<br />
<br />
I have checked the IPMI event log and it is empty, sensors are also reporting everything in normal state.<br />
<br />
The system seems otherwise quite happy (except the load of ~11, which is not normal - it is normally around 1) and it is currently serving ~5500 mariadb queries per second (which is normal too). <br />
<br />
I will be happy to provide any additional information.
