Experience High CPU after upgrade from PIX ver 6.2(2) to 6.3(3)

From the show processes command, we observed that the intf1 counter incrementing regularly.

There are sufficient memory space and the connection count is not high.

STUDENT-PIX-PRI# sh mem

Free memory: 934876624 bytes

Used memory: 138865200 bytes

------------- ----------------

Total memory: 1073741824 bytes

STUDENT-PIX-PRI# sh mem

STUDENT-PIX-PRI#

STUDENT-PIX-PRI# sh xlate count

1583 in use, 33723 most used

STUDENT-PIX-PRI# sh xlate count

STUDENT-PIX-PRI# sh conn count

May be you are under DOS attack! Try to implement this command and see if there is any improvement

ip verify reversepath inside

When you type "show xlat" do you see any IPs that dont belong to your address space?

Thanks
