error while loading database file

i have a database file which i load using your sample code:

var Datastore = require('nedb')
  , db = new Datastore({ filename: 'p.nedb' });
db.loadDatabase(function (err) {
  // Callback is optional
  // Now commands will be executed
    console.log("finished", err);
});

then i get this error:

⇒  node nedbtest.js
finished Error: "toString()" failed
    at Buffer.toString (buffer.js:528:11)
    at tryToString (fs.js:445:15)
    at FSReqWrap.readFileAfterClose [as oncomplete] (fs.js:436:12)

any ideas? i could send you the file if it helps (it is 35mb zipped, 639mb unzipped, but i previously had the error with smaller files as well). the error is not catchable…

thanks for looking into this

This would probably be relieved with PR #463.

@KeitIG I call update at line 60 in this file. I can confirm that the items does update and are registered with the same ID in the database file, with older versions towards the top of the file and the newer copy on the bottom.
