With the active use of LLD and API for adding and deleting items in dynamic environments using calculated items and the time shift function of triggers, the value cache is cleared rather slowly ([value cache|https://www.zabbix.com/documentation/4.0/manual/config/triggers/expression?s[]=value&s[]=cache#value_caching], |

It looks like currently if failed to allocate required memory then will remove items from value cache that were not accessed in last 24 hours, this is controlled by ZBX_VC_ITEM_EXPIRE_PERIOD. One of solutions would be to cleanup with some frequency, could it be enough in your case ? |
