What's wrong with my Nikon SB 600?

The problem I have with my Nikon Speedlight SB-600 is that it just won't stop triggering.
I put fresh batteries in, turn it on and the flash loading noise is audible. Once the flash is loaded, it is automatically triggered. This goes on permanently, hereby draining my batteries and preventing me from taking pictures.
Can anybody help me out with this?

How are you wanting o trigger it? Do you have radio triggers? If so anything could be sending the signal out. A TV remote, a robot vacuum, wireless headphones, the FBI spying on you anything. I had a air conditioner that made my DVD press pause.

Try to use it on a diffrent grouping and channel and see if that stops it.
