Zabbix server is not running - out of memory

Dobrý den,

používám monitoring Zabbix na Linux CentOS serveru a z ničeho nic přestal Zabbix fungovat, resp. se ve web rozhraní Zabbixu zobrazuje hláška "Zabbix server is not running". SELinux je vypnutý a v logu jsem zjistil následující:

Díky za pomoc

ODPOVĚĎ

Dobrý den,

jak uvádí log Zabbixu "please increase CacheSize configuration parameter", tak je potřeba v souboru /etc/zabbix/zabbix_server.conf zvýšit limit pro CacheSize. Pak to pojede...
