Node.js - events.js:154 throw err write EPIPE; Program Crashing

Quoting doc

EPIPE: A write on a pipe, socket, or FIFO for which there is no process to read the data. Commonly encountered at the net and http layers, indicative that the remote side of the stream being written to has been closed.

The steam maybe a pipe or socket when the other end has terminated the connection. It's a run-time error; there is nothing you can do but close your end as well.

Please check if there is one big file written or long http package request in your program.

With the following code could make your program exit successfully in this case:

process.stdout.on('error', function( err ) {
    if (err.code == "EPIPE") {
        process.exit(0);
    }
});
