in reply to Re^3: forkManager PID 1 less than top
in thread forkManager PID 1 less than top

or if the actual offset is subject to system timing?

On more secure systems, the pid is picked randomly, not sequentially. I didn't think anyone still did sequential pids! What system are you using?

    Where did you see random PIDs ? I think all (most?) Linux distros use sequental. http://en.wikipedia.org/wiki/Process_identifier#Unix-like
    Process IDs are usually allocated on a sequential basis

    Also:

    http://lists.freebsd.org/pipermail/freebsd-security/2010-February/005549.html

    I am running Ubuntu with 3.8 kernal, PIDs are sequental.
    Also, I think there can be problems with some software, when recently-used PID re-used too fast.
