I have Cisco 2610 router and occasionally it crashes.
Did You manage to capture the crash message?
I kind of suspect it had do something with IP Input but not very> sure. Here is output
Dircm#sh proc cpu | include CPU
CPU utilization for five seconds: 50%/15%; one minute: 37%; five
minutes: 32%
Nothing looking very wrong, apart from the fact, that 35% of the
CPU load comes from processes running on the router, not from
switching the traffic itself. And as You already found out:
Dircm#sh proc cpu | include IP Input
25 3562017 1980128 1798 27.59% 20.18% 18.74% 0 IP Input
The process responsible for the load is IP Input. So, Your router
is not switching the traffic in the optimal path (CEF switching),
but drops to fast or process switching for some reason.
Make sure CEF is turned on, it's on on the IP interfaces (via
'sh ip interface'), and then try to find a reason by looking at
output of 'sh cef not-cef-switched'. There's bunch of docs on cisco.com
that help to troubleshoot high CPU load - look for them using the
search box.
