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.
