zabbix server won't start

[elham_jahany]

I compile zabbix 3.2 on centos (with db2)
when I enable "DBSchema" configuration (in zabbix_server.conf) the zabbix_server can not start.
I change the debug level of zabbix server to 5 and the result is :


tail -f /var/log/zabbix_server.log

i have no idea about this problem.
db2 configuration is set and every things is OK and web installation steps is pass but zabbix_server can not start
