Why doesn't Zabbix start?

Question

linux

Good day. Zabbix has been standing and working for a long time, right now I sat down to add computers to it, in the process of adding (added 30 pieces), zabbix wrote that "The server is not running"... judging by the log, it sins from memory... but I don't understand what it is from wants me)
Help pls...
Free disk space - getting it, RAM too
