Node-xmpp: Cannot read propery 'write' of undefined

I'm having an issue with node-xmpp, server-side settings out of my control maybe have changed but this error is relatively new. Looking for some pointers/insight, I've not been able to solve this issue within the module or my code. I unfortunately cannot provide my code 开发者_运维问答to troubleshoot, however, it's on the simple xmpp.Client/send method. It's failing about 80% of the time is the kicker.

Thanks

Here's the source from connection.js in question:

Connection.prototype.send = function(stanza) {
if (!this.socket.writable) {
    this.socket.end();
    return;
}

if (stanza.root) {
    var el = this.rmStreamNs(stanza.root());
    var socket = this.socket;
    el.write(function(s) { socket.write(s); });  // LINE 76
    return el;
} else {
    this.socket.write(stanza);
    return stanza;
}
};
