%SYS-3-CPUHOG: Per minute Job

Dear All,

I am facing an issue with one of my router . Accessing the rouer is sometimes for few seconds is hard and feel some delay in sometime while working on it. you can see below output takken from router. I dont understand what could be the problem. We are observing packet loss on the link and when i saw the utilization i suspect si it due to CPU or something ?

Please let me know your findings and if you need more output let me know to provide you

-traceback=0x41155B68 …………..

nbr changed down ,interface goodbye received..

please tell me  how do i solution?

You should consider moving away from EIGRP and its many defects.

problem, and upgrading to a version in which the bug is integrated will most probably solve the issue.

Hi Inayat,

Thanks for the email. I upgraded IOS before. i was trying a luck. but u did a good experiment and reached to the exact point of upgradation.  You are great.

Please also let know how to decode the traceback ?

Highlighted

Hi Shajil,

We dont have any external tool to provide to decode the traceback.

I had decoded your traceback and its exactly matching the bug which I stated above.

CSCsl49350 <http://cdetsweb-prd.cisco.com/apps/goto?identifier=CSCsl49350> CSCsl49350

which is a non-process impacting Bug. The Symptoms and the workaround for

this Bug is as mentioned below.

Symptoms

  An IOS router that has been configured with large amount of Static Virtual

IPsec tunnels (sVTI) could experience CPUHOG errmsg from the process of

Per-minute Jobs.

Condition

This issue shows up when all of the below conditions are met:

  a) large amount (500-2000) of static VTI tunnels has been configured

  b) the ipsec negotiations for those tunnels have been failed, and by  design the sVTI, it will keep negotiating for IKE/IPsec SAs until all the

tunnel have been brought up (sVTI can only be up when IPsec SAs are up).

Workaround

  1) shut down all the sVTI tunnels, and then unshut a small number (~50)

     at a time to bring them up, then thep-by-step to bring all the other tunnels; or,

  2) use crypto map or tunnel protection (GRE+Ipsec) configuration
