Hi,

Since yersterday my zabbix-server stops serveral times.

in Zabbix self i got the error:

Connection to Zabbix server "localhost" refused. Possible reasons:
1. Incorrect server IP/DNS in the "zabbix.conf.php";
2. Security environment (for example, SELinux) is blocking the connection;
3. Zabbix server daemon not running;
4. Firewall is blocking TCP connection.
Connection refused​

The mariadb server is running and accessible.

After restart server it is running for serval hours but agin i got this error
