Deleting site results in hung processing

Here is what happened.

I did an Active Directory import and many new sites were created from OU's. I did not want that, so I deleted the sites. When I deleted the sites, it asked what i wished to do with the requesters associated to those sites. Once I selected my option and clciked OK, a "Processing" box appeared and shortly after the sites were deleted.

Then I was attempting to find the proper setting to turn off importing OU's as sites. I tested my settings by performing a new import and all the sites were created again. I am not attempting to delete the sites again, and there are some that will not seem to go away. the "Processing" box appears and spins, but nothing happens. Currently, I have one attempt that says processing and has for about 40 minutes.

Any idea why this is happening and how I might fix it?
