High CPU Utilization Due To TTY Background Process

[Mutondo.S]

Hi

I have a Cisco switch and the utilization is going crazy, i have ensured that line con 0 does not have logging synchronous as it was identified to sometimes cause the high utilization (Cisco bug ID CSCed16920 or Cisco bug ID CSCdy01705). I have added some information about the subject below:

Model: ME-3600X-24FS-M

IOS: me360x-universalk9-mz.154-3.S.bin

Process: 54   321169424    48625898       6604 57.85% 57.14% 57.12%   0 TTY Background  

Reboot: Has Not Been Performed. Will Have To Be Scheduled.

Does anyone know of a way to resolve this ?

Thank you.

This means 15.4(3)S.  Because the "S" doesn't have any digit that means this is "version ZERO".  SO I'll be expecting heaps of bugs.  

Does anyone know of a way to resolve this ?

Since there is going to be a reboot scheduled, I'd strongly recommend upgrading the IOS.

Hi Leo

Thanks for the help. I shall perform an upgrade of the IOS and revert.

Hi Leo

So after the reboot, the CPU utilization is now running at normal. An IOS upgrade had to be scheduled for a separate date. 

Thanks for the help.
