    Hello all,

    We have a web site that use the Telerik component RadUpload version 2.4.1.0 to upload files with size up to 2 Gb into a DFS folder (underneath is 2 Windows 2003 file servers for redundancy).

    Several times a day, we see this error below in the logs :

    Event code: 3005
    Event message: An unhandled exception has occurred.

    Question: is there any way to catch this error more gracefully? Or even better, do the newer versions of the radupload component have fixed it?

    Best regards,
    Sam

    Hi Sam,

    We had a similar error in the previous versions of RadUpload for ASP.NET, but it was fixed in the subsequent releases. It was caused by a glitch in the RadUploadHttpModule, which incorrectly determined that a file has ended and closed the stream.

    RadUpload for ASP.NET Ajax is much more stable in terms of file handling, that's why I would recommend that you use it instead.

    Kind regards,
