Bulk upload error

I have successfully managed to upload before but suddenly I cant do that any more. I find the following error in the currentlog.config:

2010-10-13 08:56:58,121 ERROR mojoPortal.Web.Global - 80.252.168.249-en-US - /ImageGallery/BulkUpload.aspx?pageid=1&mid=3

Any Ideas?

Re: Bulk upload error

This error can occur for a wide variety of reasons but the most common issue is file system permissions. Probably something changed about your hosting environment file permissions. It could also happen if you ran out of allocated disk space.

Hope it helps,

Joe

Re: Bulk upload error

I can see, with FTP, that the file actually is uploaded but i can't see it on the page.

Re: Bulk upload error

Is it anything more that I can do to zoom in the problem?

Re: Bulk upload error

make sure /App_Data and /Data folders are writable by the user that is the identity on the application pool.

see the docs about file uploads

http://www.mojoportal.com/supporting-large-file-uploads.aspx

if /App_Data is not writable then it can cause a permissions problem because then it uses windows/temp to upload and that puts funky permissions on the file

Re: Bulk upload error

No, sorry. All users is permitted to do everything. The file is uploaded but there isn't any thumbnails created and nothing is showed in the gallery.

Re: Bulk upload error

New information. When I upload the original file, a jpeg from the camera, then everything goes okay. That file is big (4310*2868) so i thought that I down size it. I used MS Paint to do the down scale (640*426). I uploaded and did get the error above. I tried again but used Gimp this time and this time it worked excellent. It's repeatable at least for me if some one find it worth to fix or maybe invoke some error handling.

I can open all files locally with several viewers with out errors.

Re: Bulk upload error

Hi,

I'm not yet convinced as you are that it is something about the file itself causing the error. If you post links where I can download the files if it produces an error for me when I upload it then I will agree with your diagnosis but not until then. The fact that the problem started suddenly after working fine for a while indicates that something changed about your environment and not likely a problem in the code.

Even if it does turn out to be a file specific issue, the error happens in the constructor of the .NET framework Bitmap class and therefore is most likely outside the scope of what I could fix. If it was caused by mojoPortal code that would be a different issue.

For now I still think it is a some kind of permission or configuration issue on your hosting environment or server. Or it is timing out or somehow not uploading the entire file and therefore corrupting the file so that it causes this error.

You never mentioned what version of mojoPortal you are using.

Best,

Joe

Re: Bulk upload error

Hi,

I tried these images and had no problems at all. you could try them yourself on demo.mojoportal.com

I stand by my original diagnosis that it is most likely your App_Data folder is not writable by the web process user so file permissions get funky on the uploaded file or some other factor is preventing the file from uploading completely so you end up with a corrupt file on the server.

Hope it helps,

Joe
