Execute program in background

Hi,

I have a BSP that starts a program when the user presses a button. The program is started with

"submit xyz and return".

My problem is that the program runs for some hours and the BSP throws a timeout after 60 seconds.

So the question is how can I start the program in a new background task. There is no need to show the result of the program on the BSP. I just want to press the button and get a note that the program was started.
