HELP!!! Too Many Connections And Won't Disconnet

While running the sitemap program we noticed that after about 8000 pages everything started timing out. Finally got the program closed thinking we would just restart the program but, no, it didn't work that way. I am getting an 1040 error (too many connection) and it's been that way for about 20 hours now. It's lock up the datebase file so that none of the sites on the server are working. All sites are down so essentially we are out of business! We were going to try to restart MYSQL but can't do that either because it say there are too many connections. Can someone please help us.
