Are there any other messages in the surrounding log lines? The lines you've included from this stack trace don't have any useful information about why the Mongo client couldn't open the socket.

Looking at this StackOverflow thread, there's sometimes a nested stack trace below the "Thread.run" line that includes a message like "Connection refused". This might indicate the reason why your client can't connect to Mongo.
