Sometime Today, Kenneth Gonsalves assembled some asciibets to say:
where the pid is stored on disk and physically 'rm' it. For example if the process is kppp, do a search for kppp.pid and rm it
eh? Pid files aren't created for all processes. It's up to the process to create its own pid file if it needs it for something. kill is the only way to kill a process. Deleting a pid file just makes that pid file not available anymore.
