    diagnosticlist = [];     userinfo = [];     alerttemplates = {};      eventemitter.emit('getusers'); }, 60000);

}

its work fine few iteration getting random errors like

    events.js:85           throw er; // unhandled 'error' event             ^ error: quit inactivity timeout

or

events.js:85       throw er; // unhandled 'error' event             ^ error: connection lost: server closed connection.

i getting error while executing app on local, remove problem have used pm2 node module process management.now working fine.
