I'm running a NodeJs server on linux and after several hours up it crashes:
events.js:72
throw er; // Unhandled 'error' event
^
Error: write EIO
at errnoException (net.js:901:11)
at Object.afterWrite (net.js:718:19)
Can anyone help me please??
Why downvoting?
I actually managed to fix it. This helped a lot: How to make a node.js application run permanently?
The problem was that the process was trying to write into a closed terminal.

Error while npm start in Windows 10
After npm install in vscode in my windows machine, I run npm, it starts but it shows the above error. I have cleaned cache but it did not solve.
I have searched on google but exception like this is not seen
events.js:180
throw er; // Unhandled 'error' event
^
This question is very similar to this one:
How can I fix ('throw er; // Unhandled 'error' event') code lifecycle?
For me personally, I fixed this exact issue by adding some missing environment variables to PATH.
C:\Windows\system32
C:\Windows
C:\Windows\System32\Wbem
My server stops with this error how can i solve it? Or what it is?

Error: read ECONNRESET
at exports._errnoException (util.js:1024:11)
at TCP.onread (net.js:610:25)
Thanks for answers
"ECONNRESET" means the other side of the TCP conversation abruptly closed its end of the connection. This is most probably due to one or more application protocol errors. You could look at the API server logs to see if it complains about something.
To know more about ECONNRESET, see this answer.
The message Unhandled 'error' event is suggesting that you are not listening for the error event in your code.
You can catch errors like these by catching the error event like the following
connection.on("error", function(err){ // handle "error" event so nodejs will not crash
console.log(err);
});
Im trying to start my node project on my node server but I keep getting a error message, the server is ready to use node, I already have some other projects installed on it but this I can't understand. Can anyone understand this error message?
events.js:69
throw arguments[1]; // Unhandled 'error' event

Error: listen EADDRINUSE
at errnoException (net.js:850:11)
at Server._listen2 (net.js:995:14)

at Server.listen (net.js:1071:5)
at Function.app.listen (/srv/www/ikonset.com/node_modules/express/lib/application.js:531:24)
The error EADDRINUSE means you already have a process bound to the port you're trying to listen on (3000 or whatever). What you should do is first STOP your other process on that port, then restart your Node app.
I have a problem with uploading binary data to my server running node.js Express.
This is my code for the post function:
And this is the error message in terminal:
I cant find any unhandled errors tho..
Thankful for any help in the right direction! :)
My app: Node.js, Express, some middleware including connect-assets and express.static.
All running on local machine (OSX, Node 0.8) in development mode (thus express.static).
Probably important details: I recently made the whole app work through HTTPS (with redirect from HTTP when necessary) and while developing I use self-signe certificate (enabled in my browser, of course).
Now, the app is often failing wit stack traces like that:
(1)
stream.js:81
throw er; // Unhandled stream error in pipe.
^
Error: write EPIPE
at errnoException (net.js:769:11)
at Object.afterWrite (net.js:593:19)

throw er; // Unhandled stream error in pipe.

Important: this happens often but not every time, so I assume this not to be a bug in my code.
I found this can be due to express.static and open files limit so I ran ulimit -n 10000 - with no effect, unfortunately.
Any ideas? This starts to be extremely frustrating.
OK, looks like I found the answer (at least I found a similar problem mentioned, tried their fix and it stopped falling):
the express.static middleware must be the last in the chain
