To test the impact of hires_hz on system performance, hires_hz values were modified to assess the server performance.
It was observed that when hires_hz=10000 server booted normally .
But when hires_hz was set to 1000000 server was getting hanged during boot.?
tried to login to single user mode by editing grub parameter by adding -s at the end of $multiboot line.
Now how to edit the /etc/system file to set the the values to defaults??
