PHP内存溢出Fatal error: Out of memory求解
Fatal error: Out of memory (allocated 786432) (tried to allocate 1572864 bytes) in E:\wwwroot\lunannews\dede\archives_do.php on line 997
后台发布文章提示如上，DEDE5.6的程序， 大约5W篇文章，流量很少几千， 任务管理器里CPU使用率5%以下，PF使用1G左右。
服务器是xeon E5606 4G内存
前几个月有过一次 我吧PHP.INI里面的memory_limit = 4000M 改到了 3000M， 现在又出现这种情况，改到4000M好了。
流量很少，内容也不多。 这个吃内存法怎么都不够吃的啊。
------解决方案--------------------
这个php文件是干什么的?
是否每次(或频率很高)?
在文件里加上memory_get_usage,找到吃内存不合理的部分贴出来再看
重点检查有循环的部分
