Hello
I would like to use the "kill" command supplied by util-linux to kill a
defunct process. I wonder if this is something not supported with the
kernel currently. (Linux note 2.6.35-25-generic-pae #44-Ubuntu SMP Fri
Jan 21 19:01:46 UTC 2011 i686 GNU/Linux).
Currently util-linux's kill, and others can't stop this process. I need
to reboot
A zombie process is already dead, so there is nothing to kill. It
remains in the zombie state until its parent process reads its exit
status. If that isn't happening, then there is something wrong with its
parent process.
This is my understanding too. as "init" is its parent process (perhaps
it was orphaned), that must have not been waiting on it correctly. The
high load 93-100% made the system un-usable, which made me wonder if it
was still running, or if the parent process was stuck checking for it to
finish.
BTW, Solaris does have "preap - force a defunct process to be reaped by
its parent" command.
I rebooted to get the system back.
Best regards, Jon
