That just increases the maximum queue length, stick it at 1Meg if you
want, the queue will shrink when it's unused, but if the client is too
slow for the stream bitrate (and you haven't mentioned any details) then
it won't keep up and eventually it will either starve at the client end
or get kicked from icecast. The large size just means it would take

Check your TCP buffers sizes as well, a larger RTT (ping) will require a
larger TCP window to maintain the same maximum bitrate.
