Hi,

One my clients 1841 Router giving following error on the Router, when i have checked after after seeing this error it may cause due to error some momory leak issue. Since its running almost newer version of IOS, can you please suggest which version IOS i can go ahead.

Router Version: c1841-advsecurityk9-mz.124-24.T8.bin

Thanks and Regard,

STN

The latest is 15.1.4M7 and that's a maintenance deployment. You could upgrade to it if you wanted (if you have enough flash space).

HTH,
John

Hi,

I'm not sure if IOS update will solve your issue as error mentioned related to NAT.
I suspect a lot of internal hosts or machines are being translated.

Could you upgrade the router's RAM or temporarily add this global command?

ip nat translation timeout x

Issue a 'clear ip nat translation' and observe again.
