In man ps, it clearly states the different states a process can have on Linux.D    Uninterruptible sleep (usually IO)R    Running or runnable (on run queue)S    Interruptible sleep (waiting for an event to complete)T    Stopped, either by a job control signal or because it is being traced.W    paging (not valid since the 2.6.xx kernel)X    dead (should never be seen)Z    Defunct (zombie) process, terminated but not reaped by its parent.Even tho X is a process state, it should never be seen. But is that correct? Is there a theoretical way to see that as a state on a process? Or is it completely 100% impossible?
Possible to see dead proccesses?
