[c-nsp] 3825 memory issue

[uugnaa]

Hello,

*Dead* is nothing but processes as a group that are now dead.


"Holding" is Amount of memory currently allocated to the process.

"Allocated" is Bytes of memory allocated by the process.

"Freed" is Bytes of memory freed by the process, regardless of who originally allocated it.

Please try on following command, you may get glue
#show memory dead 
#show memory debug unused
#show memory
#show processes

Hello,

I'm using 3825 router to provide internet for ADSL customers. Last week I configured policy-map to provide different bandwidth usage. Since this time my routers memory usage goes up.

border-r#sh processes memory sorted allocated
Processor Pool Total:  143619888 Used:  118621160 Free:   24998728
     I/O Pool Total:   36699648 Used:   10651088 Free:   26048560

I have several questions.

1. What is *Dead* process ? it takes many memory why ?
2. Is there any unknown process working ?
3. How do I decrease memory usage ?
4. What is column of memory real usage ?

Sincerely,
Tseveen.
