Mongodb shutting down

I have this problem with mongodb shutting down. It is actually throwing a segmentation fault and then shutting down. The error log is given below. Could anyone suggest what is causing the error.

Here are the 2 options I can think of:

1. Start your local server as a slave to the remote master. Once all the data is replicated on your local, shut it down and bring it back as a regular (master).

2. Start your local server. Use db.copyDatabase() or db.cloneDatabase()API from the command line client to copy that database from the remote server to your local server.

Please give these a try - I am positive you'll see some progress.
