keystone application crash when enable 'trace'

keystoneForjoyce.zip

Firstly, we do npm install to install dependencies, then we just add

var appmetrics = require('appmetrics');

to application, and run the application, it runs good:

[root@joycevm1 keystoneForjoyce]# node keystone.js

......

Then, we add such a line after the require('appmetrics') line:

appmetrics.enable('trace');

then restart the application, it crash at once:

[root@joycevm1 keystoneForjoyce]# node keystone.js
