I would assume you're either out of memory or that the remaining memory is so fragmented that it's essentially unusable. Is this router receiving one or more full BGP tables from peers?

Hi

Yes, you are right that my memory is fragmented and yes i am receiving full BGP routes from peers. Can you advise how should change this?

Thank you

MK

A reboot may fix the fragmentation temporarily, but the better solutions are a) getting more memory, or b) reducing the number of BGP routes that you receive from peers.

Hello,

I am not sure if more memory helps. I would rather try to find out the source for the fragmented memory. If you execute the show proc mem command, check for processes with a high number of allocs. If you execute the show mem all and the show mem sum command, check if these processes actually have a lot of fragmented memory blocks assigned in various locations. Are you actually running something like policy-based routing ?

Regards,

Georg
