I'm guessing that the alarm threshold coded in Nagios is set to alarm on a value without regard to number of cores. I'd have a look at the scripts and make adjustments such that the number of cores is taken into account.
I just peeked at one of our larger machines (255 cores) which is showing this load average:
Depending on the sophistication of the scheduler, it is very possible to end up with a machine that is more heavily loaded. It's also possible that the load is more evenly balanced than it appears from the Nagios alarms, but the other machines are just running under the threshold value.
Hi,
I am seeing very high kernel usage and very high load averages on my system (Although we are not loading much data to our database). Here is the output of top...does anyone know what i should be looking at?
Thanks,

we have an unix system which has
load average normally about 20.
but while i am running a particular unix batch which performs heavy

reduces to 15.
how can we explain this situation?

SIBA(4) BSD Kernel Interfaces Manual SIBA(4)NAME
siba -- Sonic Inc. Silicon Backplane driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:
device siba
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
siba_load="YES"
DESCRIPTION
The siba driver supports the Sonic Inc. Silicon Backplane, the interblock communications architecture that can be found in most Broadcom
wireless NICs.
A bus connects all of the Silicon Backplane's functional blocks. These functional blocks, known as cores, use the Open Core Protocol (OCP)
interface to communicate with agents attached to the Silicon Backplane.
Each NIC uses a chip from the same chip family. Each member of the family contains a different set of cores, but shares basic architectural
features such as address space definition, interrupt and error architecture, and backplane register definitions.
Each core can have an initiator agent that passes read and write requests onto the system backplane and a target agent that returns responses
to those requests. Not all cores contain both an initiator and a target agent. Initiator agents are present in cores that contain host
interfaces (PCI, PCMCIA), embedded processors (MIPS), or DMA processors associated with communications cores.
All cores other than PCMCIA have a target agent.
SEE ALSO bwn(4)HISTORY
The siba device driver first appeared in FreeBSD 8.0.
AUTHORS
The siba driver was written by Bruce M. Simpson <bms@FreeBSD.org> and Weongyo Jeong <weongyo@FreeBSD.org>.

Host mode is not supported at this moment.
