So all of a sudden, after a week of using it, I get an error message on my zabbix server gui (http://localhost/zabbix/.)
zabbix server
The error says: Zabbix serve
Zabbix serve
i had similar problem and my gui reported problem with cache, i change it zabbix-server.conf to 32M and now is ok, zabbix is an intelligent tool, please if it possible check problems in gui first. I had to much hosts ... for default cache.
