Всем привет!
Работает Zabbix (около 600 узлов, на отдельном хосте крутится его БД.)
Параметры хоста БД - проц - 4 ядра, 4 гига оперативки.
Проблема - постепенно уменьшается свободная память.
v# free -hm
total used free shared buff/cache available
Mem: 3.9G 3.4G 110M 5.1M 412M 297M
Swap: 2.0G 42M 2.0G
