Linux Server restarter on background process

[Tatuy1]

I need to close the terminal to work, so I have a problem with the server restarter (in server save).
I use the command

while true; do ./otserv; done

and then I use

ctrl + z

to stop de process. Finally with the

 disown -h %1

and the

bg 1

I can run it on background and it works perfectly, but it not open again at server save. I think the while true; do is not working. Can you help me?
