[c-nsp] memory leaking in IOS 12.2(58)SE1 on 2960's

[Tóth András]

Hi Jiri,

Did you have a chance to collect the output of 'sh log' after logging
in via console? If yes, please send it over.
Did you observe a crash of the switch or only the error message?
How many times did you see this so far? How often is it happening?
How many 2960 switches running 12.2(58)SE1 do you have in total and on
how many did you see this?

If the switch is working fine now, I would recommend monitoring the
memory usage and the rate of increase. Check the logs around that time
to see if you find anything related, such as dot1x errors, etc.

Also, consider collecting the following commands when the error
message is seen again and open a Cisco TAC case if possible.
sh log
sh proc mem sorted
sh mem summary
sh mem allocating-process totals
sh tech

Best regards,
Andras
