Hi Stefan, I am working on a similar task, an R Interpreter for Zeppelin. Since I started from scratch my version is still quite essential (e.g. no completion and no knitr yet) but I'm not getting your error. I can execute multiple R paragraphs while keeping different Rserve sessions (one per notebook) On the other hand I'm facing some problems with graphics, I'd like to include the beautiful R plotting capabilities in my Interpreter but (I still don't know why) it isn't working yet. However tomorrow I'll push my local repo so if you want you can give it a try to see if it solves your run-and-restart issue.
