Any clue?

I think the problem happens with JPG files (not opened at the same time nor previously).

I can't say it 100% sure but in tests I have done today only JPGs fail.

Thanks

Hi, we are having this error when uploading files via FTP:

org.apache.commons.net.io.CopyStreamException: IOException caught while copying.

The error appears randomly, often when uploading several files at the same time but sometimes it appears when uploading one file too.

Any idea? Is it a bug?
