cisco m9100 MDS cpu state discrepencies

[buzzy00000]

Hi.

I have weird issues with my m9100 MDS's cpu. After CISCOWorks complains that thoses equipement were peaking at 100% every minutes or so, I went on the equipements and try'd a few "show system ressources". Here is the result (remark the cpu states in bold);

It appear, sometime, for an unknown reason, CPU peaks to a weird % number (I thought a % couldn't get higher than 100).

Also, trying a "show process" (to get the running processes) command dosen't work. I am only able to "show processes"

Did someone experience same kind of discrepencies? I am running m9100-s2ek9-mz.4.1.1b.bin image.

Thank you.

Seen a lot of  incorrect CPU utilization values due to bug CSCte81951. Note the new spelling of the command to see the cpu history etc.

From bug info:

"show system resources" shows high cpu usage even when there is not much activity on the switch.

In the specific case reported the cpu util (user+kernel) was always 100%.

No workarounds. Use "show processes cpu history" or "show processes cpu" for

cpu util. Fixed in 4.2(4) and 5.0(1a).
