Hi Damien,
I believe your analysis is good in the last mail. By default
liquidsoap only has one thread for tasks such as downloading. This
would be a good explanation for one stream "stopping" because it can't
get its downloads fast enough, when you add other streams that also
perform long downloads. Here is the relevant setting for fixing that
issue (taken from liquidsoap --conf-descr):
## Generic queues
# Default: 1
set("scheduler.generic_queues",1)
# Comments:
# Number of event queues accepting any kind of task.
# There should at least be one. Having more can be useful to avoid that
# trivial request resolutions (local files) are not delayed because of
# a stalled download. But N stalled download can block N queues anyway.
In your case I'd set it to the number of streams performing large downloads.
Now, your streams are not really stopping when they fail to download,
but just playing silence thanks to mksafe(). However, streaming pure
silence is a bad idea with most codecs, so I'd advise you to not use
mksafe(), replace it by some noise or a default file (download it once
and for all, so that single("<that file>") will be infallible).
One last thing: mplayer (like many other players) doesn't really
support reading OGG streams, but only reads the first track and then
stops. This is explained in our FAQ, with ways to work around the
players' limitations. It's probably not the top issue for now, but you
should keep it in mind when testing with mplayer. A player that
properly reads streams is.... liquidsoap! (Simply use liquidsoap
'out(input.http("<your stream>"))'.)
All this should help fix the problem and understand better what's
going on. Using telnet (if only for debugging) would also be useful to
monitor downloads.
Hope this helps,

David
