Wordpress上有几个线程。组织讨论这个问题，但没有解决方案。我刚从localhost（MAMP）变成了一个实时服务器（Dreamhost），在提交操作（比如更改标题）或尝试在管理员中加载页面（比如post/page/cpt列表）时，我得到了恒定的404。

问题是WP运行时内存不足（请参阅下面的支持消息）。在WP admin中评估/排除内存使用故障的最佳系统方法是什么？插件往往与这类问题有关；还有其他常见的嫌疑犯吗？

`I\'ve checked into why you\'ve
been receiving these 404 errors, and it seems your scripts have been
getting automatically killed by our Process Watcher script due to your
site(s) going over Memory limits on the shared server.
