CPU 99% with 'show config'
Hello Chris,
I have double checked the symptoms and I
made some research about it.
I found that this behaviour has been seen
before and
documentation under the following number: CSCsh15587
You can find some more information about
under the following link:
http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCsh15587
From
the release notes:
Symptom:
When executing "show conf", high CPU
utilization can be seen.
This happens from ver7.0, and does not
happen in ver6.3(4) and 6.3(5).
Conditions:
Use ver7.0 or later configuration size is
large (default config does not show the issue)
- This would explain, why this is
behavior has not seen on version 7.2(3).
- Please let me know if you have any
further question.
Have a nice day.
Sincerely,
Tamas Csallo

If you are running ASA/PIX version 7.x then
you may need to upgrade to
version 7.23 to avoid your firewall running at 99% CPU utilization. There is
a bug in Cisco ASA/PIX version 7.01-7.22 that causes the firewall to run
to 99% CPU utilization when a telnet (or SSH) session requests large
quantities of data (which FirePlotter does frequently).
