Zabbix Server not running.

[BattleOP]

I logged into my Zabbix interface this morning and noticed an error that said "Zabbix server not running: the information displayed may not be current". No changes overnight to the server (I'm currently the only admin that knows about this server) but it was working last night before I was done for the day.

I logged into the CLI and restarted Zabbix and I'm still getting the message.

It's a recent install from about a week ago. So I'm running the most recent version and the most recent LTS version of Ubuntu. I'm running this on a VMWare ESXi server with local storage to the server.


The log file has the following message on restart:

Any ideas? Google and the forum search turns up nothing. What I have found the log shows Zabbix does not like.

[BattleOP]

Can anyone point me in the right direction?

A workaround is specified in the log message.

16791:20200619:153546.945 [file:dbconfig.c,line:95] __zbx_mem_malloc(): please increase CacheSize configuration parameter

Please try adjust the CacheSize setting.
