Hello,
we have a problem when a host goes down the "zabbix agent unreachable" trigger is fails if the housekeeper running. The only solution we found is to restart the zabbix server. Someone has seen this issue before?
Every other function is working properly.
We got two servers with 44 cores and 512GB RAM in a cluster. (pacemaker/corosync) Zabbix server runs on the first one and the databse (MariaDB, mysql Ver 15.1 Distrib 10.3.9-MariaDB, for Linux (x86_64) using readline 5.1) on the second one.
