我正在尝试使用DAM管理屏幕将资产上传到CQ5 DAM。我能够成功上传大小高达5 MB的文件。上传大小大于5 MB的文件时，我收到一条错误消息"无法上传以下文件："。这种情况发生在支持HTML5的浏览器(FF)和非HTML5浏览器(IE)中。
当我在firebug控制台中检查POST请求时，我收到一条错误消息，要求我检查服务器中的错误日志。以下是我在错误消息中得到的内容，
服务器遇到内部错误或配置错误，无法完成您的请求。请与服务器管理员联系，webuser@localhost并告知他们错误发生的时间，以及您可能做的任何可能导致错误的事情。服务器错误日志中可能提供了有关此错误的更多信息
但当我搜索错误日志时，我找不到任何与上传失败有关的内容。
我在网上搜索了一下，但找不到这个问题的任何解决方案。如果有人遇到同样的问题并解决了，请告诉我。以下是我在OSGI控制台中查看最近的请求时得到的信息

当移动巨大规模的资产时，最好在您的系统中配置WebDAV[1.XP中的新网络连接；2.为windows 7映射网络驱动器]或任何类似Bitkinex的WebDAV客户端[http://www.bitkinex.com/download]适用于windows、cyberduck、mac/ioS的webdrive。
