    Zabbix Value cache continuously exhausting

    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. I started monitoring the value cache and saw that it was going down again.

    Since then I have not made any changes.

    Each restart of the server clears out the cache but afterwards it slowly starts to runs out again.

    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
