我正在尝试使用 dam 管理屏幕将资产上传到 CQ5 DAM。我能够成功上传最大为 5 MB 的文件。我在上传大小超过 5 MB 的文件时收到错误消息“无法上传以下文件：”。这发生在支持 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。请联系服务器管理员 webuser@localhost 并告知他们错误发生的时间，以及您所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有关此错误的更多信息。
但是当我搜索错误日志时，我找不到与上传失败相关的任何内容。
我在互联网上搜索，但找不到任何解决此问题的方法。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 控制台中检查最近的请求时得到的结果，
