ETIMEDOUT exception makes my app crash

[Davevb]

When my Node script returns an fatal error like this:

**events.js:182
throw er; // Unhandled 'error' event
^

Error: connect ETIMEDOUT 172.16.12.5:3000
at Object.exports._errnoException (util.js:1024:11)
at exports._exceptionWithHostPort (util.js:1047:20)
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1150:14)**

I can't catch it in my C# code and my program crashes.
