These are processes that are dead and have exited, but they remain as zombies in the process list. The kernel keeps them in the process list until the parent proces retrieves the exit status code by calling the wait() system call. This does not usually happen with daemon processes because they detach themselves from their parent process and are adopted by the init process (PID=1) which will automatically call wait() to clear them out of the process list. You may sometimes see the daemon defunct PID in the process list for a brief moment before it gets cleaned up by the init process. You don't have to worry about these. You can also end up with an unkillable process if a process is stuck waiting for the kernel to finish something. This usually happens when the kernel is waiting for I/O. Where you see this most often is with network filesystems such as NFS and SaMBa that have disconnected uncleanly. This also happens when a drive fails or if someone unplugs a cable to a mounted drive. If the device had a memmapped file or was used for swap then you may be really screwed. Any kernel calls that flush IO may hang forever waiting for the device to respond.]]> linux sysadmin unix https://pinboard.in/ https://pinboard.in/u:mlednor/b:4a2de8b831a0/ 2013-01-15T10:53:31+00:00 http://alias.sh/ mlednor bash unix shell linux https://pinboard.in/ https://pinboard.in/u:mlednor/b:f3803807446e/ 2012-10-05T16:07:37+00:00 https://github.com/progrium/skypipe mlednor cloud unix network https://pinboard.in/ https://pinboard.in/u:mlednor/b:33dd293b9e4b/ 2012-09-21T09:58:44+00:00 http://acme.com/software/micro_httpd/ mlednor webserver embedded unix https://pinboard.in/ https://pinboard.in/u:mlednor/b:9bc91f7fc826/ 2012-08-28T08:45:38+00:00 http://www.cyberciti.biz/open-source/command-line-hacks/pv-command-examples/ mlednor linux tips unix https://pinboard.in/ https://pinboard.in/u:mlednor/b:e1401fae5e93/ 2012-02-05T08:59:34+00:00 http://matt.might.net/articles/ssh-hacks/ mlednor ssh unix sysadmin network https://pinboard.in/ https://pinboard.in/u:mlednor/b:9a24e1508ac6/ 2011-09-19T11:53:19+00:00 http://tychoish.com/rhizome/9-awesome-ssh-tricks/? mlednor ssh unix linux security https://pinboard.in/ https://pinboard.in/u:mlednor/b:e30da958d050/ 2011-07-11T16:26:56+00:00 http://h.ackack.net/cheat-sheets/netcat mlednor unix network security cheatsheet https://pinboard.in/ https://pinboard.in/u:mlednor/b:5a06547d5724/ 2010-09-23T08:50:40+00:00 http://www.cyberciti.biz/tips/spice-up-your-unix-linux-shell-scripts.html mlednor bash linux programming scripting unix https://pinboard.in/ https://pinboard.in/u:mlednor/b:faf6728ef9b6/ 2010-08-08T20:14:36+00:00 http://mxcl.github.com/homebrew/ mlednor mac software unix https://pinboard.in/ https://pinboard.in/u:mlednor/b:abace69c9f4a/ 2010-02-24T17:45:10+00:00 http://www.mysysad.com/2008/01/ftp-using-shell-script.html mlednor unix scripting https://pinboard.in/ https://pinboard.in/u:mlednor/b:50cc8fc956b9/ 2010-02-12T16:23:38+00:00 http://www.ibm.com/developerworks/aix/library/au-badunixhabits.html?ca=lnxw01GoodUnixHabits mlednorunix shell https://pinboard.in/ https://pinboard.in/u:mlednor/b:22937787b31e/ 2009-12-25T12:30:27+00:00 http://shell-sink.blogspot.com/ mlednorshell unix https://pinboard.in/ https://pinboard.in/u:mlednor/b:c3643812065b/ 2009-12-24T18:49:18+00:00 https://help.ubuntu.com/community/BIND9ServerHowto mlednorunix sysadmin https://instapaper.com/ https://pinboard.in/u:mlednor/b:f4a1728e92fa/ 2009-12-03T16:13:33+00:00 http://www.commandlinefu.com/commands/view/4169/set-your-ssd-disk-as-a-non-rotating-medium mlednorunix https://pinboard.in/ https://pinboard.in/u:mlednor/b:c84dc29c3ea9/ 2009-11-29T09:07:30+00:00 http://www.cuberick.com/2008/11/update-bash-history-in-realtime.html mlednorshell unix https://pinboard.in/ https://pinboard.in/u:mlednor/b:f5073a989668/ 2008-10-09T06:35:24+00:00 http://www.linuxjournal.com/content/bash-extended-globbing mlednorunix linux bash tips https://pinboard.in/u:mlednor/b:c49ed1b76726/
