Re: Zombie process displays no information

Have you tried 'Tree' view, F5, in htop?  This gives an ASCII art view of the running processes by parent-child relationship.  Pressing F5 again will toggle the view back to normal.

That may give you some information.  The 'ps' command may be used to find out more, possibly, but I'm too unfamiliar with 'ps' to give you much assurance this will work:

$ ps -u root -U root --format pid,euser,ruser,fname,comm,args

If I saw this on my machine, I would be strongly tempted to kill the process and see if anything bad happens.  I'd at least reboot and see if the noname process reappears.

Re: Zombie process displays no information

ps -ef has the PPID column which is the id of the process' parent.
