I am coming from riak and redis where I never had an issue with this services starting, or to interact.

This is a pervasive problem with mongo and am rather clueless. Restarting does not help.I am new to mongo.

MongoDB shell version: 2.2.1
connecting to: test
Fri Nov  9 16:44:06 Error: couldn't connect to server 127.0.0.1:27017 src/mongo/shell/mongo.js:91
exception: connect failed

This is what I see in the logs.
