I haven't followed this thread, so I apologize if this answer has already been given. If you have a process that is stuck in a zombie mode and kill -9 isn't getting rid of it, you may need to do something with the parent process that spawned it in the first place. Often, child processes will hang around for no apparent reason, until the parent process has ended. ps -ef | grep <PID> or ps -eaf | grep <PID> will give you the parent process ID as well as the current PID. The parent process ID is in the third column, as shown here: $ ps -eaf | grep sshd root 3979 1 0 Aug27 ? 00:00:00 /usr/sbin/sshd root 10872 3979 0 08:09 ? 00:00:00 sshd: XXXXXX [priv] XXXXXX 10874 10872 0 08:09 ? 00:00:00 sshd: XXXXXX@pts/0 First column: Process owner Second column: PID of the sshd process(es) Third column: PID of the process that spawned sshd So, if my pts/0 shell won't go away, with PID 10874, the parent process would be PID 10872. You could kill that process, and PID 10874 should end along with it. -- Mike Burger http://www.bubbanfriends.org Visit the Dog Pound II BBS telnet://dogpound2.citadel.org or http://dogpound2.citadel.org To be notified of updates to the web site, visit: https://www.bubbanfriends.org/mailman/listinfo/site-update or send a blank email message to: site-update-subscribe@xxxxxxxxxxxxxxxxx -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
