  I will test using this command, however I have never used Valgrind
and know absolutely nothing about it. But I'll try to log its output to
file.

  I use it on the Debian 7.2 (stable) system.   The OS is running on
the virtual private server.
  I compiled the IceCast package by myself and created a .deb-file for
it. After that I installed this .deb-file as an ordinary Debian package.

  The songs are usually about 3 to 5 minutes long -- a usual radio
format.

  According to my observations, every IceS stream adds some memory
leak. It was true both for the Icecast-2.4beta3 and Icecast-2.4beta4.
The only difference I noticed was in the actual leakage rate. It was
bigger for beta4.
  If you still have my old graph for beta3, you can see the transition
from the band #4 to #5. One of the IceS instances (the smaller one --
for the single stream) was turned off at that point. And one may
clearly see a sharp	change in the memory leakage rate (from 80
bytes/sec to 50 bytes/sec).

  Please let me know if I can help in some way. I'll do my best.
Meanwhile let me see what Valgrind shows.

  Regards,
    Vladimir
