Hello.

I've upgraded Zabbix server installation from 3.4.15 to 5.2.1. All database's changes completed successfully and zabbix server started up. After a couple of hours suddenly it has crashed with SIGSEGV. I'd restarted zabbix server and whole virtual machine, but it didn't help: every time I get the same SIGSEGV error shortly after server's startup.
Both versions of zabbix server are built from source, OS version and all the environment are the same.
Zabbix server error log and config log are attached. Could you please check it and give an advice, what should I fix?
