kipmi0 is using almost 100% CPU

[prahn]

Hi!

I have two ESX 3.5 Servers, almost exactly the same hardware setup with an Intel Mainboard

and a CoreDuo Quad CPU. the first one has Update 2 installed (this one runs fine!) the second

one has Update 4 installed.

I setup the second machine in April (uptime now 160 days) with a base insatllation disc

containing ESX 3.5 update 4. Yesterday I saw in the performance graphs, that this machine

uses 100% of one CPU core. Looking via TOP on the CLI I found that the process calld "kipmi"

uses this many cpu power:

12:23:19 up 160 days, 20:53, 1 user, load average: 1.00, 1.00, 1.00

117 processes: 115 sleeping, 2 running, 0 zombie, 0 stopped

CPU states: cpu user nice system irq softirq iowait idle

The output of ESXTOP looks like this:

I searched the community and also with google, and found some things, but nothing helped:

I tried restarting the pegasus service with "/etc/init.d/pegasus restart", I also tried to kill

the process with -9, but I can not stop this process from running

For now I did not try a restart of the host, as I suspect it will come back

after restarting....

What else can I do?
