knife ssh - jetty will stops suddenly - linux

Question

I have a chef infrastructure with chef-server/chef-client. I want to restart jetty from all machines using knife ssh.
There is a very strange behavior. When the jetty starts, it receive a kill signal and it stops. This is happening only when I'm using knife ssh.

the command used to restart jetty is:
knife ssh -x root "name:*" "sh /opt/jetty/jetty-current/bin/jetty.sh start"
As I said above, if I execute the command from ssh, manually on each machine(without using knife), jetty starts and works fine. What something else knife ssh does instead of make a ssh on each machine and runs that command?
I've tried to fix this different ways including using & at command / creating another shell script that executes the command, but without any success.
Here is a paste2 with jetty.sh
There is something that kills jetty when I start it using knife. Have any idea what?
Edit: tried to put jetty.sh into /etc/init.d/jetty and start as a service with service jetty start, but there is the same result.

I've found a workaround which I used to solve the problem.
The thing is that knife ssh once finish execution, will kill every spawned process. Maybe there is a bug with this.
I've created a cookbook and inside it a recipe where I run service jetty restart. Then, using knife ssh I only execute this recipe from chef-client.
