Django / FCGI Issue

Over the weekend, my Django powered website suddenly stopped working, only returning 500 Internal Server Errors. When viewing my logs, I get the following:

codeNo such file or directory: FastCGI: failed to connect to (dynamic) server
"/home/merlin903/": something is seriously wrong,
any chance the socket/named_pipe directory was removed?, see the
FastCgiIpcDir directive[/code]Does anybody have any clue what this means, how to fix it, and/or how I can prevent this from happening in the future?
