每当我尝试使用 mongo 的交互式 shell 时，它都会死掉：
somekittens@DLserver01:~$ mongo
MongoDB shell version: 2.2.2
connecting to: test
Mon Dec 17 13:14:16 DBClientCursor::init call() failed
Mon Dec 17 13:14:16 Error: Error during mongo startup. :: caused by :: 10276 DBClientBase::findN: transport error: 127.0.0.1:27017 ns: admin.$cmd query: { whatsmyuri: 1 } src/mongo/shell/mongo.js:91
exception: connect failed
我能够修复安装（删除mongodb.lock等）并回到这一点，但它只会再次死去。

使用节点的外壳连接：
> mdb.open(function(err, db) { console.log(err) });
[Error: failed to connect to [localhost:27017]]
我四处寻找这个错误，并没有发现任何用处。这是在相当旧的服务器上运行的（Ubuntu 12.04 32 位，640MB RAM，500MHz P2）。我怎样才能解决这个问题？
