See if this helps. The engine behind the Atrium Integrator that actually runs the jobs remotely is called Carte server. It is a component of Pentaho Suite you use to run jobs remotely. While installing Atrium Integrator, Carte also gets installed on each node. At the run time Atrium Integrator sends the job to Carte and Carte executes them. Carte is an apache web server listening on default port 20000. While the job is running in the AI Console you can see a status button, when you click the button, it actually launches the Carte url. >From there also you can control the job runs.(Stop,Restart etc..) Coming to AI jobs controlling in a Server Group, while scheduling the job in the AI Console you can select which carte Server(each ARServer will have one Carte server installed) this job should be associated with. You can have one instance of job run in only one node. You cannot loadbalance or concurrently run the same job run instance across multiple ARS nodes.
Probably you might have to kill the AI Plugin or restart Carte Web Server or restart ARS itself depending on the kind of issue you are seeing.
