1.　根据网上说法，　/etc/php.ini下修改了配置将128换成了2048

#memory_limit = 128M

memory_limit = 2048M 

重启httpd服务  发现没有生效.依旧报这个错 提示内存还是128M，无效

2. 修改http/conf.d/下面的zabbix.conf  将128M换成512M

重启httpd服务再次刷新界面  依旧无效

3.对于前两种方法都无效，所以只能尝试，修改php页面，根据log提示，可以看出访问的php页面是

/usr/share/zabbix/include/db.inc.php 
所以编辑改文件，在头部添加

set_time_limit ( 0 );
ini_set("memory_limit","-1");

 

 重启http服务后发现问题解决
