Apple has issued Pro Applications Update 2008-003, which updates both Compressor and Qmaster to 3.0.4.

However, some of our clients were reporting more qmaster unresponsiveness than before the update, sometimes rendering qmaster irreparably unresponsive (say that three times fast).

Below then is a script that can completely wipe your install of Qmaster/Compressor. You can then reinstall from scratch the AppleQmasterNode.mpkg from the Final Cut Server installation disk, and then use Software Update to get it back to 3.0.4. All this without disturbing a running Final Cut Server. (Obviously, qmaster processes will fail during the reinstall, but if you're at this juncture, your qmaster is probably not working anyway.)
