Uploads "Stuck" and CPU overages

[stoneaccents]

Some people have had trouble completing their uploads, this is the first time in over 10,000 uploads that it has happened.
Here is how the lady that monitors the gallery put it.

You know when you upload a LO and it then comes up with a second screen where you can add keywords etc?? I guess something kind of like that is coming up again showing the LO's are stacking up and not uploading. One girl could delete them but another could not. She says she can't open anything so that they can be deleted.
I have been trying to find a way to clear uploads that are 'stuck' in the upload process.

I have no idea of where to start to fix this. I have also been getting a lot of CPU overages in the last week but this is the first time the uploads got stuck.

Thanks for the help, it won't make much sense to my until I work through it but your instructions are clear.

Yes posting more exactly the error you get would also help us assist you but the post above is the most common issue with uploads and using GD2.
