Thanks in Advance

[Leo Laohoo]

No but the IOS you currently are using can be potentially the cause of your high CPU.

Upgrade to  12.2(55)SE8.  This is a very stable version.

[alireza1368m]

Thanks Leo

i did it, but the problem still exist

[Leo Laohoo]

Post the output to the command "sh proc cpu | ex 0.00".

I've never seen this before.  And your switch stack is running 12.2(55)SE8?

Something in your configuration is triggering "Adjust Regions".

[alireza1368m]

yes i upgrade to 12.2(55)SE8 as u said

unfortunately there is no document to give me a idea about this process

[Jared McMillan]

I am having this same issue on a C3750X stack running 12.2(58)SE2.  One 3750X running IP services and the other base.

Did you get this resolved by any chance?  I have only have 1 other 3750X stack running the same ver and i dont have this problem there.

[kmoorman1]

I have the same problem but i think its related to an acl and route-map config. going to remove it in the next week and I will let you know how it goes

[paul driver]

Sorry wrong post

Sent from Cisco Technical Support iPad App

[INGENIERIA Y CONSULTORIAS WEBREDES LTDA]

did you had some command on your running-config like

access-list hardware region

let us know.

[Jared McMillan]

Just went through the configs and I do not.  Installed another 3750X stack with same ver and having same issue.  It must be something in the config but nothing stands out.
