I use phpmyadmin ( package phpmyadmin 4.0.10-1 ), I usualy start manually apache and mariadb :

systemctl start mysqld
systemctl start httpd

and I stop manually apache and mariadb :

systemctl stop httpd
systemctl stop mysqld

but a zombie process appears just after the shutdown of httpd and mysqld : httpd ( the owner of the process is "http" user ), the bug is triggered only if I use phpmyadmin,

systemd is unable to shutdown this zombie process ( the command "systemctl stop httpd" ), the only way is to do a "killall -9 httpd",

If I don't use phpmyadmin then there is no zombie process ( httpd ) after the shutdown of httpd and mariadb services by systemd,

Additional info:
* package version(s) phpmyadmin 4.0.10-1, apache 2.2.25-1, mariadb 5.5.34-3

* config and/or log files etc.

Steps to reproduce:
- start manually apache and mariadb with systemd
- use phpmyadmin
- stop manually apache and mariadb with systemd
- a zombie process ( httpd ) will appear
- if you see no zombie process then restart the procedure, because it's sometimes a random bug
This task depends upon

Sounds like an apache bug. And if systemd is not able to stop the service there might be an issue, too.

Have you tried reproducing this with an older phpmyadmin version?

I use the last version of the package phpmyadmin ( 4.1.1-1 )

the bug is still here, a zombie process ( httpd, owned by "http" user ) who doesn't want to be closed if myphpadmin was used, a "killall -9 httpd" is the only solution to close this process

I cannot reproduce this with Apache 2.4, it might be fixed. Can you confirm?
Comment by patrick (potomac) - Sunday, 09 March 2014, 16:09 GMT
yes, the bug seems resolved with apache 2.4
