[icecast] Darkice memory leak

[Kristjan Gu?ni Bjarnason]

I was looking more closely on the source for Darkice.  I found the code for
calulating the buffersize somewhat strange.  Your is snapshot taken from the
init function in CastSink.cpp :

    int       bufferSize = bitRate ? (bitRate * 1024 / 8) * bufferDuration
                                   : (128 * 1024 / 8) * bufferDuration;
    bufferedSink = socket ?  new BufferedSink( socket,
                                     (bufferSize * 1024 / 8) *
bufferDuration)
                          : 0;

In my case the bufferDuration is 10 and bitrate 128.  Why is the do we
multiply by 'bufferSize*1024/8*bufferDuration twice?
The constructor for BufferedSink allocates the buffer with the 2nd param as
the buffersize.  In my case the 'chunkSize' is 1 which gives bufferSize =
209.715.200 bytes.  I am wrong?  Is this healty?

<p>Unfortunately I can't reproduce your memory leak reports. For example,
here is the line about my production darkice instance from top:

   PID USER     PRI  NI  SIZE  RSS SHARE STAT %CPU %MEM   TIME COMMAND
27516 root      20   0  3564 3564  1340 S    95.6  1.3  47:06 darkice

<p>this as after approx 50 minutes from start, but the memory load doesn't
change for the whole 4 hours it runs.

What's even more strange, is that darkice does not allocate memory
itself after initialization. I can only guess that the only place memory
can leak is in the libraries darkice uses.

Kristjan or Nicu, can you send me the exact libraries that you'r using?
