OpenBSD network crash



Hi,

I've make a test with a IXIA 400 Traffic Generator/Performance
Analyzer to test Linux kernel 2.2,2.4, FreeBSD 5.1 and OpenBSD
3.4 to certificate for rfc2544.
 
http://www.faqs.org/rfcs/rfc2544.html

These are the result:

Linux Kernel 2.4

     %TxtPut  11.22 30.30 CRASH

OpenBSD crash and pc reboot.

Hardware Notes.:

Celeron 733Mhz with 126Mb RAM.
Two NIC are realtek 8139c chipset using rl* driver.

Why OpenBSD crash?

Any Ideas?
