[cisco-nas] 7206 PPPoE NAS crashed

[Souphonh Phounsavath]

Dear Mounir Mohamed,

Thanks for your suggestion. CPU utilization is very low, but the I/O memory
usage is high. See my show memory history below:

The processor memory is low, but the I/O memory is high. How can I dedicate
more memory for I/O?

Hi,
 
Check the crash file which is stored on the router internal FLASH the
problem may be related to IOS problem use (Router#dir all - then use
Router#more crash_file_Name ) to check the crash files, also once the case
happen again try to check the CPU and memory may be the below access-list
consume the box cpu due to an virus attackes from your LAN, many kind of
problem can lead your router to do that so you have to monitor the box. 
 
Best Regards,
Mounir Mohamed

I hate to say it, but you are running bleeding edge code. 12.2 or
12.3 is stable and will run for years. Do you need 12.4 for some reason?
