[cisco-nas] Memory leak or a bad PC?

[Michael Taylor]

Hi,

It looks like a bug, but NOT with the windows box.

I put the "show ver" and traceback messages into the output interpreter 
(stack decoder) and it thinks that it is this bug:
http://www.cisco.com/cgi-bin/Support/Bugtool/onebug.pl?bugid=CSCdz30206&Submit=Search

"CSCdz30206 - 12.1(13)E1: buffer leak middle pool due to Remote Console 
Process"

And it is fixed in 12.1(13)E03 or higher.

Time to upgrade, OR, try and minimise telneting into the switch to do 
config and commands...

Best Regards,
Mike Taylor
