Hi at all,
I have a Zabbix server V5.0.3 with CentOS8 and monitor about 300 server.. Have a problem on "Zabbix value cache working in low memory mode" .. but this not expected..if I see the graph seems something bug.. a see free 80% and all of a sudden it goes below the threshold .. to raise it just restart the zabbix-server service
Any ideas?
