It happens when I used https://github.com/mscdex/node-imap on io.js 1.4.1 (on mac os).
On <= 1.3.0 node-imap worked good.

[bnoordhuis]

Can you report this to mscdex/node-imap first, please? It might be a bug in that module that flew under the radar until now. If not, @mscdex should holler and I'll reopen the issue. Thanks.

[vkurchatkin]

It looks like node-imap is pure js, so it is probably io.js bug

workaround;
deps/uv/src/unix/stream.c
int uv__stream_open(uv_stream_t* stream, int fd, int flags) {

#if defined(__APPLE__)
   enable = 1;
   if (setsockopt(fd, SOL_SOCKET, SO_OOBINLINE, &enable, sizeof(enable)) &&

-      errno != EINVAL) {
     return -errno;
   }

@gnostic do you have a way to reproduce this issue? what you do reverts libuv/libuv@19d3d50

[mscdex]

@bnoordhuis As @vkurchatkin said, imap is pure js, so the error is happening in io.js C++ land.

[sergenikitin]

io.js v1.4.2 has the same problem.

[rvagg]

@sergenikitin are you on Windows? if so, see #1005 and perhaps #1008 is relevant?

[sergenikitin]

@rvagg no, OS X 10.10.2

[rvagg]

/cc @indutny this looks relevant to your stream changes

[indutny]

@gnostic does following patch fix the problem for you?

@indutny
I checked this patch, it's not fix the problem. Still have

[indutny]

@sergenikitin is there any way to reproduce it?

[indutny]

Ok, a test case:

var tls = require('tls');
var net = require('net');

var socket = new net.Socket();

var s = tls.connect({
  socket: socket,
  servername: 'google.com'
}, function() {
  console.log('secure');
});

socket.connect(443, 'google.com');
