Node red crash with bad node parameter

I'm new to Node-Red. It's happened to get Node-Red crash by changing one of node parameters (Modbus TCP - ip address); moreover Node-Red failed to re-start due an uncaught exception during loading of flows.
Eventually, i changed manually of json flows file by using back door and all started back.

And here question: Are there should be a better handle in back-end for managing such scenarios?
I'm come from industrial automation and from my point of view one bad flow should not interference with other and whole server.
Or i did some wrong, or here more things to config?
any feedback appreciated, thanks.
