I use MakeMKV 1.17.4 on Linux Mint 21.2 Mate.
Overall it works quite well, but I noticed that MakeMKV produces during its operation zombie processes.
I found two situation where this happens always in a reproducible way:
I open makemkv via the mintmenu. This work fine and ps -ef shows (my username is mike):
Code: Select all
mike 2116 1899 0 11:18 ? 00:00:02 mintmenu
mike 2616 2116 1 11:19 ? 00:00:22 makemkv
mike 2625 2616 8 11:19 ? 00:02:42 /usr/bin/makemkvcon guiserver A0001+shm
During the opening process I see via ps -ef:
Code: Select all
mike 4347 2625 0 11:51 ? 00:00:00 /usr/bin/mmgplsrv libdvdnav-server
Code: Select all
mike 4347 2625 0 11:51 ? 00:00:00 [mmgplsrv] <defunct>
(Afaik this happens only when I open DVDs and not when opening BRs.)
The second action that produces a zombie process is when I eject a DVD or Blu Ray via the Eject button in the MakeMKV toolbar.
In this case ps -ef shows after (working) ejecting:
Code: Select all
root 4655 2625 0 12:03 ? 00:00:00 [umount] <defunct>
When I close MakeMKV these zombies also vanish.
Is it possible to avoid these zombies altogether?
