I have a rails application, running in development mode ( with a sqlite database ). The application's purpose is to allow users to upload files through a java client.

If a user wants to upload a folder, all the files inside it will be recursively uploaded. If a user wants to upload a file, the file will be uploaded normally.

Here's the error I'm receiving :


 IOError

    in UploadedFilesController#new

closed stream

Here is the application trace :

I have no clue why this happens ... the client gets to upload about 15-30 files ( from a folder, through the java client ) before this error appears. I am running Rails 2.0.2 . Could the fact that I'm running in development mode using sqlite as a database cause this ? Any help would be greatly appreciated !

Thanks guys !

I think I've figured it out, at least I think I do ( the client just keeps on uploading now, error-free ) . After you read data from a file that you upload, you should also CLOSE it. Who would have thought? :P

I'd agree, but do you know why that matters? Are you running out of space in some way?
