Zabbix Server Hangs at shutdown: "A Stop Job is Running for Zabbix Server"

[patrick.thomas]

Hello Everyone,

I am running Zabbix 4.2.8 on Ubuntu 18.04.3

I've had a new Zabbix install working on site here for a month or so now, but whenever I try to reboot or shut it down the above error occurs. Can anyone advise on how best to troubleshoot this? I'm a novice when it comes to Linux, and installed the above following a guide that has otherwise resulted in a successful install.

Any advice is appreciated.

Many Thanks

Just to add, from my searches it looks like similar problem was reported here, and that it is because MySQL is stopped before the Zabbix Server is, and so Zabbix won't quit because it's trying to find the MySQL instance. But other than this, I don't understand how to resolve this.

In https://support.zabbix.com/browse/ZBX-15602 there is some info about the solution. In my Zabbix 4.4.4 (which should be fixed according to the case) there is:

$ cat /lib/systemd/system/zabbix-server.service
[Unit]
Description=Zabbix Server
After=syslog.target
After=network.target
After=mysql.service
After=mysqld.service
After=mariadb.service
...

If you have a specific reason why you cannot upgrade to a supported Zabbix version, you may want to try editing the service file manually.

And I believe something like "sudo systemctl daemon-reload" is needed after editing the service file.

Hi Markku

Have now upgraded to 4.4 from 4.2 and can now confirm that the services stop as expected, with shutdowns and reboots working correctly.

Thanks for your advice, and for pointing me in the right direction.

On the test server, when restarting the server, the problem "A stop job is running for Zabbix Server no limit" appears. If for example MySQL stopped working.

The solution to this inconvenience. In the file /lib/systemd/system/zabbix-server.service
Change the value

TimeoutSec=infinity to TimeoutSec=240s

Update the settings

systemctl daemon-reload
