zabbix 5.2.6不定时重启， 日志报错 failed to open log file: [24] Too many open files

问题说明：zabbix server 不定时重启

问题表现：

1、页面会提示 《 Zabbix server is not running: the information displayed may not be current .》,如下图所示

 

 

2、/var/log/message 会提示

systemd: zabbix_server.service: control process exited, code=exited status=1

systemd: Unit zabbix_server.service entered failed state.

systemd: zabbix_server.service failed.

systemd: zabbix_server.service holdoff time over, scheduling restart.

 

3、/var/log/zabbix_server.log 会提示

zabbix_server [27012]: failed to open log file: [24] Too many open files

zabbix_server [27012]: failed to write [cannot accept incoming IPC connection: [24] Too many open files] into log file

 

优化方式：

#查找defines.inc.php文件
find / -name defines.inc.php

#编辑defines.inc.php文件
vi /usr/share/zabbix-ui-5.2.6/include/defines.inc.php

#找到ZBX_MAX_GRAPHS_PER_PAGE
将20该大即可
