Nodejs express server goes down when some error occur

Question

I am using Express as my Node.js web framework with MongoDB as persistence layer. When I run the server with 'node app.js' command, and occasionally some error occur such as mongoose error or imagemagick error, the hole node process will die and not available from browser. I used Express' error handler but this is still happening. Can someone help?

What version of node are you using? I got around this using the clusters package and the process.on('death') message. Look at the example code for clusters on the node.js website — ControlAltDel

process.on('uncaughtException', function (err) {
  console.error(err);
  console.log("Node NOT Exiting...");
});
