Thanks, David. :-)
I tried simply replacing mksafe with fallback, but I got a "this source
is fallible" error. So I did this:
#!/usr/local/bin/liquidsoap
set("log.file.path","/home/audiodef/liquidradio.log")
set("log.level",4)
output.icecast.vorbis(host = "localhost", port = 8000,
password = "lazysusan", mount = "ambient.ogg",
mksafe(fallback([playlist(timeout=600.,
"http://audiodef/playlists/ambient.m3u";),
single("http://audiodef/audio/dc3.ogg";)])))
What this does is after 600 seconds of silence, the stream plays the
fallback file and then plays silence ad infinitum. With this, my
previous recipe:
#!/usr/local/bin/liquidsoap
set("log.file.path","/home/audiodef/liquidradio.log")
set("log.level",4)
output.icecast.vorbis(host = "localhost", port = 8000,
password = "lazysusan", mount = "ambient.ogg",
mksafe(playlist(timeout=600.,
"http://audiodef/playlists/ambient.m3u";)))
the stream played the files in the playlist but ended up playing silence
ad infinitum after the first track.
What could be causing my stream to end with endless silence?
Here's the playlist, in case it matters:

Here's the log from this attempt, set to level 4. I did read it
carefully, and don't see anything show-stopping. There's one failed
file, but liquidsoap should simply move on to the next one, right?
That's what it seems to do, in writing, but in practice, I'm getting
silence after the first track:
