Question: It's obviously good for creating dummy data; also can be used for generating passwords (although I believe you have to be careful here as to the true "randomness"). Any other useful uses that you've come across?

Answer: 
Contact Microsoft Support Services (PSS). Make sure the issue also happens on the most current version of your server (i.e. full updated service packs and patches). MS will gladly issue a patch free of charge for a production issue.

Regardless how you turn the table, a server should not crash on a RPC issue. Point. This is a bug you encountered that needs patching.
What's the error that is being returned? Check the mini dump files in the SQL Server Log folder to get more information about the actual reason for the crash.

You'll probably need to open a ticket with Microsoft and have look into the bugcheck that is causing the crash.

Before you call make sure you have the most recent service pack and hot fix installed. That will be the first thing they want you to do.
