hi ,

after insertion of SFP module in  the Switch i have messages bellow and the switch hangs after couple of minutes it restarts

*Mar  1 01:19:58.729: %SYS-3-CPUHOG: Task is running for (2098)msecs, more than (2000)msecs (13/11),process = hpm main process.

-Traceback= 1381038 13810CC 12F6260 10A59F8 10A5B70 12F7CD4 12F7AF8 12F6D7C 13BEDEC 13BF03C 13C05D4 13C084C 13C1280 1457BB8 145949C 1460F20

I Check out the below link for information on %SYS-3-CPUHOG on switches

http://www.cisco.com/en/US/products/hw/iad/ps397/products_tech_note09186a00800a6ac4.shtml

" CPUHOG at the Time of an OIR

CPUHOG messages are common at the time of an OIR, because the router has to perform a set of complicated and relatively long tasks. There is no need to worry about CPUHOG messages that occur during OIRs, as long as the card that was inserted comes up properly. "

Cisco said "there is no need to worry ..." but in my case the Switch hangs and after 4 or 5 miniutes it restarts.

i upgrade the IOS version to the latest but i still have the problem.

any help plz

thank you

Does the problem go away if you take the SFP module out?

What type of device is this?

Hi Reza ,

thank you for your reply

Does the problem go away if you take the SFP module out?

     => yes exactly.

What type of device is this? 

    =>WS-C2960S-48FPD-L , IOS : c2960s-universalk9-mz.122-55.SE3

Hi,

Can you try a different SFP?

Is this a Cisco SFP optic or from a 3rd party?

HTH

Hi ,

yes i try different SFP ( SFP works perfectly in other Switch with the same type)

the SFP is for Cisco

thank you

Usually, Traceback messages indicate memory issue.  So, you can upgrade to a later version of IOS and see if the message disappears. If that does not help, open a ticket with TAC and RMA the switch.

Upgrade to 12.2(55)SE7.

Hi Leo

I tried to upgrade to 150-2.SE3 but we still have have the issue.

thanks

I tried to upgrade to 150-2.SE3 but we still have have the issue.

1.  You DO NOT want to load 15.0(2)SE3 unless you really want to cry.  Avoid this particular version at all cost.  Major TACACs bug! 

2.  I recommended 12.2(55)SE7 and nothing else. 

Hi Leo ,

i tested the IOS version 12.2(55)SE7 , but we have still the problem

I suspect a hardware issue.

Thanks
