 Description   

New installation of Zabbix 3.4.1 with MariaDB DB.
Everything worked fine for a couple of hours. Now Zabbix Server is suddenly constantly crashing. Re-installation does not help .There are no errors in MySQL logs.

I am attaching the Zabbix Log.

Could you please be so kind and provide libcurl version, also increase log level of alerter:
./sbin/zabbix_server -R log_level_increase=alerter and attach the log ?
