High CPU is due to memory leak/memory fragmentation. 

Reboot the router is the workaround.

thank you for replied me.. i have tried but again after 30 min the same issue continued

please suggest permenent solution .

Add the two green values and the total is the RED value. 

This means when the memory drops any further from 3005364 the router will crash. 

Permanent solution is to stop using the 1800 router to do NAT plus overwhelming the WAN link.  

without nat is possible to connect internet ..???

What is the WAN link for the 1800 router?

Post the complete output to the command "sh version".

wan 100 mbps 

 

I think it is disrespectful to laugh out at a question. It is obvious that the person does not know the right way and he has reached out to the community to help

Kailash, 

 

100 mbps is too high with NAT enabled for the 1841 to handle. You should go for a bigger router. In case you need some guidance on router selection please do reach out

your suggestion is correct but that same 1841 router is worked fine in past 1 year. how is possible

same router same wan 100mbps is workied fine in last 1yr. suddenly got problem

I do not believe an 1841 router is capable of hitting 100 80 Mbps even with a "clean" config.
