I am trying to upload assets to CQ5 DAM using the dam admin screen. I am able to successfully upload files with sizes up to 5 MB. I am getting an error message "failed to upload the following file : <FILENAME>" while uploading files with sizes greater than 5 MB. This happens in both HTML5 supporting browsers (FF) and non-HTML5 browsers (IE).

When I checked the POST request in the firebug console, I got an error message asking me to check the error logs in the server (see attached : Error_Console.jpg). But when I searched the error logs, I couldn't find anything related to the failed uploads.

I searched over the internet but couldn't find any solution for this issue. Please let me know if anyone has faced the same issue and resolved it. Below is what I got when I checked the recent requests in OSGI console,
