rebooting node.js cluster workers

rebooting node.js cluster workers


I have a node app I use cluster to run on multiple cores.

I'm running into an issue where when my app throws an exception, the Worker dies and doesn't restart. That makes sense, but I'm wondering if there is a better way to handle restarting these workers instead of having to monitor it or try/catch or listen for every error.
