I think I'm having the same problem. I am running MySQL 4 as well, with 
fairly recent SVN:

Library API version: 0.19.20060331-1
Source code version: 9824
Options compiled in:
 linux debug using_lmsensors using_v4l using_oss using_alsa using_ivtv 
using_lirc using_x11 using_xv using_xrandr using_frontend using_backend

What happens to me is that usually around a program change, or when a 
couple of programs start recording, the backend just goes away. It's 
still running, and still recording, but the frontend cannot connect to 
the backend. If I stop and start the daemon, it will pickup and start 
recording again, and then the frontend can connect. What can I do to 
help debug this?
