mongo db.shutdownServer()期间出错

当我尝试在我的VM Ubuntu中关闭mongodb时出现以下错误.

我正在运行12.10 Ubuntu无头服务器.

目前的Mongodb Shell版本是2.0.6

use admin
switched to db admin
> db.shutdownServer()
Tue Dec 10 14:17:03 DBClientCursor::init call() failed
Tue Dec 10 14:17:03 query failed : admin.$cmd { shutdown: 1.0 } to: 127.0.0.1
server should be down...
Tue Dec 10 14:17:03 trying reconnect to 127.0.0.1
Tue Dec 10 14:17:03 reconnect 127.0.0.1 ok
Tue Dec 10 14:17:03 Socket recv() errno:104 Connection reset by peer 127.0.0.1:27017
Tue Dec 10 14:17:03 SocketException: remote: 127.0.0.1:27017 error: 9001 socket exception [1] server [127.0.0.1:27017] 
Tue Dec 10 14:17:03 DBClientCursor::init call() failed
Tue Dec 10 14:17:03 query failed : admin.$cmd { getlasterror: 1.0, w: 1.0 } to: 127.0.0.1
Tue Dec 10 14:17:03 Error: error doing query: failed shell/collection.js:151

我该怎么办？

我试图关闭它的原因是因为我想更新到mongo 2.2.

请指教.
