Zabbix錯誤”zbx_mem_malloc(): out of memory”解決方法

Zabbix Server突然掛了，查看log報錯如下：

using configuration file: /etc/zabbix/zabbix_server.conf
...
[file:dbconfig.c,line:545] zbx_mem_malloc(): out of memory (requested 16 bytes)
[file:dbconfig.c,line:545] zbx_mem_malloc(): please increase CacheSize configuration parameter

報錯里已經很明確的提示了修復辦法：please increase CacheSize configuration parameter

所以，我們就去zabbix_server.conf中找到CacheSize字段

### Option: CacheSize
#   Size of configuration cache, in bytes.
#   Shared memory size for storing host, item and trigger data.
#
# Mandatory: no
# Range: 128K-8G
# Default:
# CacheSize=8M

根據服務器配置情況，修改CacheSize

### Option: CacheSize
#   Size of configuration cache, in bytes.
#   Shared memory size for storing host, item and trigger data.
#
# Mandatory: no
# Range: 128K-8G
# Default:
CacheSize=2048M

重啟Zabbix Server即可

systemctl start zabbix-server
