Nodejs express server goes down when some error occur

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?
