zabbix out of memory( 内存溢出) 解决

今天把zabbix2.2.0升级到了2.4.0，服务端启动成功了。但是在管理界面下 Zabbix server is running 是NO  就去看了下log  发现了几个错误

解决
      打开zabbix_server.conf 找到 Option: CacheSize
      把原来的 # CacheSize=8M  前面的#注释去掉，将8M修改为1024，这个1024根据服务器性能修改。

### 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=1024M
