Steps to reproduce:
1. Create instance with zabbix server and database
2. Stop database
3. Check tail -f /var/log/zabbix/zabbix_server.log
You will get infinity log stream:

1729485:20251125:211208.621 [Z3001] connection to database 'zabbix' failed: [2002] Can't connect to local server through socket '/var/lib/mysql/mysql.sock' (2)
1729485:20251125:211208.621 database is down: reconnecting in 10 seconds

4. After >60sec check systemctl status zabbix-server and make sure that server is active.

Expected behaviour:
zabbix-server instance will stop after 60 sec of inability of connection to DB.
