Lately I've been seeing a lot of "The IO Thread was interrupted" error message which made me think. I know what this means but I'm a java programmer. This is an inappropriate message for a typical end user who will likely not know what either "IO", "thread" or even "interrupt" means in this context. Furthermore, it doesn't tell me which file had the problem.

This message should be changed to something like "filename could not be uploaded because servername closed the connection" or something like that. You can probably do better than that, but you get the idea. Test out the error message on a few non-programmer friends and see if they understand it.
