zmq crash when creating 118 sockets

zmq-crash.js

var i,
    zmq = require('zmq'),
    numSocks = 1000,
    sockets = [];

console.log('MAX_SOCKETS=' + zmq.Context.getMaxSockets());

console.log('creating sockets');

for (i = 0; i < numSocks; i++) {
  var sock = zmq.socket('dealer');
  sockets.push(sock);
  process.stdout.write(i + ',');
};

console.log('');

console.log('done creating sockets');

for (i = 0; i < numSocks; i++) {
  sockets[i].close();
};

console.log('done closing sockets');

Output is
