Zabbix Server will not start

[dazza007]

Having setup my server and added my first few devices my zabbix server stopped and won't start. I have tried changing the memory settings according to http://alekseymyshkin.ru/zabbix-memo...-not-starting/
I am on ubuntu 18 with Zabbix 4.2, some updated similar post on the forums show problems also with VMware, where I am using HyperV.
Help please

service zabbix-server start
Job for zabbix-server.service failed because the control process exited with error code.

I am guessing these two lines point to your problem:

36148:20190518:195014.522 [file:dbconfig.c,line:94] __zbx_mem_malloc(): out of memory (requested 256 bytes)
36148:20190518:195014.522 [file:dbconfig.c,line:94] __zbx_mem_malloc(): please increase CacheSize configuration parameter

Edit the config file to allocate more memory and see if that solves your issue.
