Hello,

A few weeks ago we received the following alert:

Less than 5% free in the value cache: Problem

We've been using zabbix for more than 6 months already and never had this problem. We have not added many new devices for monitoring during this time.

I checked the server config file and saw that the value cache was set to the default one which is 8M. I set it to 16M and restarted the server. This is the reason of the big change in the graph on 8th of March. I started monitoring the value cache and saw that it was going down again and restarted it on 13th or March.

Since then I have not made any changes.

Please help me finding out what could be the reason of that. It was working for many months without problems and there were not any changes to the configurations prior this problem.

the version of zabbix is 3.0.1 by the way.

Thanks
