CPU High utilization over 4500

[Varun K S]

Hi All

Any suggestion

for the below logs found over 4500 , also CPU utilization is over 95%

Mar  9 08:52:10.857: %C4K_IOSIPROUTEMAN-3-ADJMANNOMOREADJS: AdjMan: hardware adjacency resources exhausted, performance may be degraded.
.Mar  9 08:52:39.276: %C4K_IOSIPROUTEMAN-3-ADJMANNOMOREADJS: AdjMan: hardware adjacency resources exhausted, performance may be degraded.

IPv4 CEF is enabled and running
VRF Default:
83179 prefixes (83179/0 fwd/non-fwd)
Default network 0.0.0.0/0
Table id 0, 0 resets
Database epoch: 0 (83179 entries at this epoch)

Why the utilization is increasing.. is there any method to reduce the utilization without clearing the adjacency and cashe.. is there any other resolution...

Thanks
Varun

Hi Varun,

There was a good discussion here

https://supportforums.cisco.com/thread/26938

A route pointing to an directly connected interface would cause such an issue.

Example

ip route x.x.x.x y.y.y.y 10.1.1.1

or

ip route x.x.x.x y.y.y.y [interface]
