When rebooting the zabbix server (redhat 7.6, systemd), the server hangs on zabbix shutdown:

"a stop job is running for Zabbix Server"

Relevant rpm package info: zabbix-server-pgsql-4.2.1-1.el7.x86_64

Since the server was patched beforehand (yum update), could that have triggered this (a second reboot didn't cause this)? Because that would mean zabbix needs to be shut down manually before patching begins.
