Howdy
We added Site02 for redundancy and DR. Also added new SAN and ESX hosts.
The CPU on device Site01Server01 is not very happy when files are being transferred between the sites.
Since the setup is the same at both sites, why is the problem only at site01?
Drawings attached, any help appreciated.
Site02 is newer and we have two 3750X-24 with IOS 12.2(55)SE3 on ipservices, for site02server01; no problem.
Site01server01 is a stack of two 3750G-24PS with IOS 12.2(58)SE on ipservices.
Some output from site01server01 switch:
site01server01#sh proc cpu | e 0.00+.+0.00
CPU utilization for five seconds: 97%/17%; one minute: 90%; five minutes: 62%

Roll-back/downgrade your IOS from 12.2(58)SEx to 12.2(55)SE1 or later. Starting from 12.2(58)SE and 15.0(1)SE, these two versions have a memory leak problem that Cisco has been trying to fix for months (particularly the former).

Thanks for the heads up.
Memory is behaving, still have plenty to spare.
The high CPU just went away, tested with high traffic loads and CPU just stayed at 6%.
Looks like it just had a cpl of off days?

If you are having a high CPU in IP Input it is best to see what exact the traffic is that is being switched
by the CPU.
A first step would be to use the show controller cpu command to determine the exact queue that increments
a lot when the CPU is high
If you know which queue traffic is on you can then run debug platform cpu 
Best to disable console loggin and just turn it on and of again after a few seconds and look with show log
what the exact packets were.

hi ,
you can implement a safe debug as follow :
(config)#no logging console (config)#no logging monitor
(config)#logging buffer 128000
after that clear the log
#debug ip packet detail
to check the trend of the traffic (which IP ,interface ..)
Regards
