Hi Tomas,
I think that you misunderstand my email, but that’s my fault for not including enough information. The SIGKILL (ie kill -9) is irrelevant. Please see https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=27140 for much more information.
Basically, it boils down to zebrasrv not propagating signals (SIGTERM, SIGKILL, whatever) to its children. (And no the defunct zombie process won’t be cleaned up until its child process exits.)
Funny enough, I don’t actually see any way to resolve this situation without patching zebrasrv or using SIGKILL (ie kill -9) to stop all relevant zebrasrv processes.

You don't just violently kill a process. You send it the signal so it closes its open connections, etc.
Of course killing it with -9 will yield an empty ps -ef.
It would be interesting to see if those defunct processes cleanup after some reasonable time.
What OS are you using? (in KTD it would mean what image, default is master-stretch, I use master-buster to develop/QA).

So I just tried "koha-zebra --restart kohadev" after making a change to log levels to include request in koha-conf.xml in koha-testing-docker and it's a mess:
root at kohadevbox:koha(bug_12430)$ ps -efww | grep "zebrasrv"
kohadev+ 808 1 0 02:04 ? 00:00:00 daemon --name=kohadev-koha-zebra --pidfiles=/var/run/koha/kohadev/ --errlog=/var/log/koha/kohadev/zebra-error.log --output=/var/log/koha/kohadev/zebra-output.log --verbose=1 --respawn --del
ay=30 --user=kohadev-koha.kohadev-koha -- /usr/bin/zebrasrv -v none,fatal,warn -k 1024 -f /etc/koha/sites/kohadev/koha-conf.xml
kohadev+ 840 808 0 02:04 ? 00:00:00 [zebrasrv] <defunct>
kohadev+ 5183 1 0 04:28 ? 00:00:00 /usr/bin/zebrasrv -v none,fatal,warn -k 1024 -f /etc/koha/sites/kohadev/koha-conf.xml
root 5373 3959 0 04:31 pts/1 00:00:00 grep zebrasrv
Using "kill -9", I kill off all those.
I run "koha-zebra --start kohadev":
root at kohadevbox:koha(bug_12430)$ ps -efww | grep "zebrasrv"
kohadev+ 5418 1 0 04:31 ? 00:00:00 daemon --name=kohadev-koha-zebra --pidfiles=/var/run/koha/kohadev/ --errlog=/var/log/koha/kohadev/zebra-error.log --output=/var/log/koha/kohadev/zebra-output.log --verbose=1 --respawn --del
ay=30 --user=kohadev-koha.kohadev-koha -- /usr/bin/zebrasrv -v none,fatal,warn,request -k 1024 -f /etc/koha/sites/kohadev/koha-conf.xml
kohadev+ 5422 5418 0 04:31 ? 00:00:00 /usr/bin/zebrasrv -v none,fatal,warn,request -k 1024 -f /etc/koha/sites/kohadev/koha-conf.xml
root 5424 3959 0 04:31 pts/1 00:00:00 grep zebrasrv
That's much better now.

Hmm then it must just be me, because "koha-zebra --stop $koha_instance" is definitely not stopping zebrasrv on my servers...
Mind you "kill" doesn't either without a -9..

for me, it successfully stops the zebrasrv process
try the following to stop zebraidx
koha-indexer --stop $koha_instance
