Hi Jos

Which version of Servoy do you use ?  
While there is no API strictly for batch processors, we have, since 8.2, the [client manager plugin](https://wiki.servoy.com/display/DOCS/clientmanager). You can list all connected clients and kill them.

We had a [webinar](https://www.youtube.com/watch?v=XUVbwpfufgc) for the 8.2 release dedicated to this plugin.

Headless clients can be (re)started from the headless client plugin. Let us know if you need more details. Good luck!
