zabbix运行过程中突然提示server未启动,重启服务无法启动，检查selinux未开，排除此问题
检查日志有如下提示。
tailf /var/log/zabbix/zabbix_server.log 1230:20180706:165735.809 [file:dbconfig.c,line:90] zbx_mem_malloc(): out of memory (requested 120 bytes) 1230:20180706:165735.809 [file:dbconfig.c,line:90] zbx_mem_malloc(): please increase CacheSize configuration parameter
找到zabbix配置 文件 增加cache大小
vim /etc/zabbix/zabbix_server.conf 378 ### Option: CacheSize 379 # Size of configuration cache, in bytes. 380 # Shared memory size for storing host, item and trigger data. 381 # 382 # Mandatory: no 383 # Range: 128K-8G 384 # Default: 385 CacheSize=2048M 386
改完后再次重启server ，正常
