Using icecast 2.3 may help, using the development version will not
(right now, I don't think it contains anything significant that isn't
in 2.3 - when it does, it probably won't be stable).

As for limits: yes, but it'll be highly platform specific, and is not
a limit in icecast itself. You'll probably first hit either a limit on
the number of threads permitted (one per source, plus a few for the
rest of icecast), or the limit on open file descriptors (one per
source, plus one per client, plus a few for the rest of icecast)

Also, icecast will be horribly inefficient for this, it's really
totally the wrong tool. Why not just make your application stream
directly to the single client that's listening to that stream?

Anyway, I can't say what limit you might have hit, or whether it's a
limit that's increasable, or how to increase it, since you didn't say
what platform you were running on. We can't guess things like that.
