"host # sysctl -p <-- Use the -p option without any arguments if you've made adjustments to your sysctl.conf file and want to reload it, or just to be sure that it is actually being read (if you have serious doubts, you can run "strace -f /sbin/sysctl -p" to get more granular information. If you find that you do need to use strace to run down a problem with sysctl, hopefully our previous post on using strace to debug application issues will help get you off on the right foot and an expedited solution)"
