Edited Issue: initial isense save saves incomplete DB [1325]

using:

```
var b = require( 'body-parser' );
var c = require( 'debug' );
var d = require( 'errorhandler' );
var e = require( 'express' );
var f = require( 'express-jwt' );
var g = require( 'jsonwebtoken' );
var h = require( 'moment' );
var i = require( 'mongoose' );
var j = require( 'morgan' );
var k = require( 'nconf' );
var l = require( 'serve-favicon' );
var m = require( 'underscore' );
var n = require( 'winston' );
```

after a few mins (<15m), you get a .dat file that is 714kb. you have to wait another 15m before the next save (300mb). the 1st save seems to be incomplete.
