Our Zabbix environment consists of separate database, server, and proxies. This is on updated 7 LTS. The web runs on the server. We came in this morning to "Zabbix Server is not running", then it would go away, then it would come back. We have noticed that if we disable the web, then the server itself does not crash. Pretty much as soon as we enable the web, boom, server crashes. I can provide almost any data if requested.
