I have this problem that I am hoping someone can help me with:

Pix 515 (R) with 64M RAM and 16MF running 7.2(3). I have outside and inside interface.

Configuration is very simple I have a Linux host behind inside interface with

an IP address of 192.168.6.10/24 and be NAT'ed as follows:

static (inside,outside) 4.2.2.2 192.168.6.10 netmask 255.255.255.255

I have web server on the outside interface with an IP address of 4.2.2.10

inside interface IP address: 192.168.6.1/24

outside interface IP address: 4.2.2.1/24

On the Linux host, I run a program called "nkiller2" that can generate thousands

thousands of http connections to hit the web server.

When I start this program, I send about 20,000 http connections through the Pix515.

Using "show conn count", I saw that when the connection reaches about 10,000 connections,

the firewall goes into reboot. After the reboot, there is NO crashinfo in the flash

(verified with show flash:). In the flash, I have nothing except pix723.bin file so there

are plenty of spaces on the flash for crashinfo file.

Issue with this Pix is that I can NOT upgrade to version 8.0(4) or download to 7.0(8)

because the pix will reboot everything 5 minutes. With version 7.2(3), it is stable until

the connection goes over 10k connections.

Has anyone seen this before? Thanks.
