我的上传速度为40KB /秒 获取闪存错误，而上传照片比我的大500kb，上传小于100-500kb的照片时无错误〜。

我的朋友有8mbit上传速度，即使上传3.2mb照片和更多也没有错误。

如何解决这个问题？

我试图重新上传IO错误触发器，但它停在相同的地方。

有关此错误的任何解决方案？

顺便说一下，我正在通过调试代理监视进程，并发现，响应头根本不会出现此IO错误。

有时会显示套接字错误。

如果需要，我也会发布serverside php脚本。但它停在

if(isset($_FILES['Filedata'])) 
{ 

所以它不会帮助:)因为所有处理都是在此检查之后发生的。

Answer 1

其实这是一个服务器问题。几个星期前，我们用Ubuntu 10.04和Apache一起开发了VDS，问题本身就消失了。

在以前的服务器上，我记得有litespeed服务器与unix。

Answer 2

听起来像服务器的问题，没有太多的动作。尝试更新php.ini以允许更大的上传限制：
