Help zabbix service not running

[nacho.im]

I am very new to Zabbix and I have the following problem.
I was adding network devices to be monitored and from one moment to the next the Zabbix UI shows me "The Zabbix server is stopped", I don't understand why if only devices were loaded.
I leave you a screenshot

You can solve it now. It turns out that in my case what happened is that in the zabbix.conf in the CacheZice section it was at 80M, I updated it to 12GB. For some reason I didn't take it either, I lowered it to 9GB and it worked perfectly. He also clarified that between changes you have to restart the Apache and zabbix services

As the log says, the problem is:

zbx_mem_realloc(): please increase CacheSize configuration parameter

Then open the /etc/zabbix/zabbix_server.conf file and increase the CacheSize
You don't need 9GB of cache.
I have +1500 Hosts and configured it with 2GB, but only 25% is used.
Increase in multiples of 32.
64MB, 96MB, 128MB, ...etc

If necessary, also increase the other Cache.

Default, minimum and maximum?
