Orphan Process =============== If in a process, the parent process is terminated before the child process, the child process become orphan - It takes the lowest possible process as its parent - And its PPID is changed to the PID of its new parent process. - Mostly the new parent process in init process (PID = 1).
In new linux systems , the orphan processes aren't always inherited by init process. A system process (in my system) 1298 adopted it . And this vary with system to system.
