[mahbobsun]

any suggestion for replacement device of this old 2600 ?

[JohnTylerPearce]

Robab,

I would like at the ISR G2 1900 series if I were you.

[JohnTylerPearce]

What happens if you do the following.

no ip route-cache

ip cef

If it were me, and you can get away with it, I would upgrade the IOS.

Also setting the 'load-interval to 30' and checking on 'show processes cpu' from time to time might be wise, to see if a micro burst is happening.
