Hi,

For 2 days, i've been encountering memory issues on my core router (6509). Here are the most usefull commands, can i tune something or must i upgrade the memory ?

Hi,

Your 6509 has 64M and uses about 10M with 54M free. This seems not to be critical or abnormal.

Which kind of issues are you encountering? Do you have any log messages or other indications you base your statement on and can you post them?

Regards, Martin

This line seems critical,

Your first output (show mem stat) shows that the router is using about 326MB of processor memory. That is pretty high. The second output (show mem alloc totals) shows that 2 functions are responsible for over 200MB of the used memory. That is a big red flag and suggests that there is a memory leak on this box (always a software problem). These 2 functions are both used by SNMP.

I think you are hitting CSCsg77142. This won't get fixed in the 12.2(18)SXE throttle, so you'll have to move to SXF. 12.2(18)SXF14 is the most reasonable upgrade path.

You'll have to reload or do a switchover to a standby supervisor to clear the problem in the meantime.
