Steps to reproduce:
1. Downloaded 2.6.0-test1 from kernel.org tree and built it, reboot
2. Installed apache server(httpd-2.0.45) on system and start it
3. Choose a client system with 2.4 kernel on it;
installed hammerhead-2.1.2;
cd to /etc/hammerhead;
vi post.scn file and put the following lines in it:
NSample GET
RGET /cgi-bin/test-cgi
T0
rm root.scn
create a hammerhead scenario file to run hammerhead:
Set up section number to be 50
Set up run time to be 96 hours
run the following command to start hammerhead:
hammerhead -c hammerhead-scenario
4. The system crashed after about 24 hours in my case.
