Early today, when DataBase went down for backup process, all the zabbix_server's processes went down too.
Daily, our database is going down about 2 minutes to take an snapshot and today is the first time it happens.
zabbix_server.conf is almost default (vanilla)
Zabbix DB: bx05d
Seems problems in the webchecks, see zabbix_server.log and PID 1608
