Zabbix Server Cache free space running up

[iamreinaldoneto]

I've got my Zabbix Server running today and then I started monitoring four Mikrotiks with snmp protocol, after a couple of minutes the service stopped and the log said to me that I might increase CacheSize parameter in zabbix_server.conf
Once I did it, the service started running normally again, but then another couple of hours past, my service stopped again with the same suggestion of increasing CacheSize parameter.
How can I resolve that?

Looks like in shot chunk of time you've added new items to monitor.

I only have 4 items, I did not added a new one yet, but my cache still getting spaceless.
Sooner, I increased Cache Size and the Zabbix configuration cache was about 70% free, now is 52%
It is about to explode, again.

So what you have now as CacheSize?

[iamreinaldoneto]

Now, my CacheSize is 128M.
I stopped the discovering rules of my items, and the cache is no increasing anymore.
However, cache value did not and is about to get 0% free.
