Hi,
I am facing a strange problem from last two days. One of my 3640 router
is behaving in a strange manner.
Sudenly it is becoming 60 - 99 % CPU utilization.(Usally 20 - 30 %) at the
same time It is droping the output packets on Main Serial link (which is
using for uplink/downlink) and input packets on fastethernet (Used for
LAN) port. Even these Interfaces are not overloading..
On the same router I am having 17 more serial links, and 1 more fast
ethernet, and one ethernet interfaces and all are in working. I am using
wccp v1, and BGP also on the same router.
After Observing the problem I did the following things.
1) Increased the hold-queue to 4096
2) stopped the wccp
and observed the status. But there is no use. It behaved in the same
pasion. So I kept the things back.
I am wondering.. if anybody help me.. The traffic is same and not
varying.. but it is very much flutuating..
Please give me suggestions.. if anybody have any idea..
Thanks,
Kiran
PS: The router is not giving this problem continuously.. for 2 mins.. its
working properly.. next 2 or 3 mins.. dropping the packets.. and next 2
mins.. working properly..
