Hi Brad, sorry for only replying a year later...

I tried to reproduce this with Xvfb 1.7.0 (the latest upstream version). I ran 'Xvfb :1' and 'for i in `seq 200`; do DISPLAY=:1 xterm -e sleep 1', and sure enough after some time I get this: [config/hal] couldn't add match rule: org.freedesktop.DBus.Error.LimitsExceeded (Connection ":1.1255" is not allowed to add more match rules (increase limits in configuration file if required)) [config/hal] cannot detect a HAL startup. Xvfb doesn't crash in this version, though, which is an improvement. In 1.6.x, Xvfb is plagued by bug#529927, so it crashes before the dbus connection limit is reached.
