CPU on Physical ESX Host is at 100%

[jauner]

I am running VMWare ESX Server version 3.5.0 update 2 on a HP DL360 saerver with 2 quad core processors with 32 GB of ram. CPU 0 keeps showing at 99 or 100%. Is there anything I can do to fix this? I just noticed it today.

Do you have processor affinity configured for proc0 on your vms?

To see what is utilizing this CPU, you need to SSH into the service console and su to root and run top, this will show you if there is a process running in the service console is consuming the cpu.

ESXTOP will show you usage levels on all of you processors.

I ran top and it looks like ftperl is using 99 - 100 % of CPU. From what I read on the communities this is related to High Availability.

I understand reconfiguring helps it but then it just comes back.

you can see the CPU utilization by core by core using ESXTOP ; Press C.

Hi,

CPU 0 is where the Service Console VM runs, most of the time you can execute top in the Service Console to find the run away app.

It is likely to be pegasus which would just need a service restart in most cases.
