Uploads a problem?

I need some explanations please. I do my duty by sharing files, but the stats confuse me on the monitor screen.

1) I only allow 5 uploads at a time, with a max of 2 per person. When the same person attempts to upload 5 from me, I see the message "upload limit reached". Will the person ever actually get this file after one of their two uploads finish? It does not appear that they do, I have monitored uploads for the last 12 hours and once that upload gets a status of "upload limit reached" it is dead as dirt.

2) Many, many, many uploads in the last 12 hours said "uploading" however the upload never takes off. It remains at 0 kbs and never shows a status (percentage of upload). Seems like these remain "dead as dirt" also.

It appears that uploading from me is certainly not in anyones favor and that is not what I intended. I wanted to limit any one person to two uploads at a time, and when one of the two was finished, AND if an upload slot was available, then this persons THIRD upload would begin. Am I wrong?
