Original GitHub issue: https://github.com/netblue30/firejail/issues/98

I'm running several applications sandboxed with Firejail. Here's what KSysGuard shows:

firejail
where soffice.bin has a "zombie" status.

firejail --list shows:

722:root:/usr/bin/firejail --profile=/home/xxx/.config/firejail/dnsmasq.profile /usr/bin/dnscrypt-proxy --ephemeral-keys --resolver-name=dnscrypt.eu-dk --local-address=127.0.0.1:41 --user=

728:root:/usr/bin/firejail --profile=/home/xxx/.config/firejail/dnsmasq.profile /usr/bin/unbound -d 
4089:xxx:/usr/bin/firejail thunderbird 
4492:xxx:/usr/bin/firejail firefox 
21067:

firejail --tree shows:

722:root:/usr/bin/firejail --profile=/home/xxx/.config/firejail/dnsmasq.profile /usr/bin/dnscrypt-proxy --ephemeral-keys --resolver-name=dnscrypt.eu-dk --local-address=127.0.0.1:41 --user=

    4494:xxx:firejail --profile=/home/xxx/.config/firejail/firefox.profile /usr/lib/firefox/firefox 
      4495:xxx:/usr/lib/firefox/firefox 
        4537:xxx:/usr/lib/mozilla/kmozillahelper 
21067:
  21068:
    21085:
      21086: (zombie)

Thus, for libreoffice only the PIDs are shown but not the process names. I had libreoffice started by clicking an .ods file in the krusader filemanager.

Did soffice.bin crash?

No, it didn't. It was still running when I made those screenshots. FWIW, it was started with a start script in /usr/local/bin (discussed in another issue here):

firejail --profile=/home/xxx/.config/firejail/libreoffice.profile /usr/bin/libreoffice "$@"

On Debian jessie seems to be working fine:

Do you still have the problem?

No, strangely enough I can't reproduce at the moment. I had observed the same phenomenon in the past days, but right now I'm not able to demonstrate it. Sorry - I'll keep watching it.

However, I still see a zombie process. Example:

10697:xxx:firejail --profile=/home/xxx/.config/firejail/libreoffice.profile /usr/bin/libreoffice --writer /home/xxx/Dokumente/Dacia.odt 
  10698:xxx:/usr/lib/libreoffice/program/oosplash --writer /home/xxx/Dokumente/Dacia.odt 
    10715:xxx:/usr/lib/libreoffice/program/soffice.bin --writer /home/xxx/Dokumente/Dacia.odt --splash-pipe=5 
      10716: (zombie)

This is what pstree shows (krusader's parent process is kdeinit5):


       │          ├─krusader─┬─libreoffice───firejail───oosplash─┬─soffice.bin─┬─soffice.bin

OK, let's keep it open for now, maybe we can get to the bottom of it. What distro are you on?

Same problem with vlc, if the file name has spaces( doesn't have "zombie" though).

EDIT: Oups, no. It's when they are weird characters, like "ö è Ũ ĐỆ Ồ Ê Chinese characters...." anywhere, in the line that --tree/--list is supposed to show, that it doesn't show. And it's universal for all applications. Probably a unicode issue. I didn't reproduce the "zombie" though, this on 0.9.34.

firejail tools doesn't even show the PID.

@pirate486743186: following up on your idea with utf8, this is what I got:

$ firejail --tree
11204:
  11205:
    11206:
      11207:netblue:sleep 120

All that is needed is an executable program with utf8 characters in the name. Thanks!
