 I'm streaming audio from Windows to Linux PulseAudio server using Netcat.
 The pulseaudio process exits without log messages whenever I kill the
 nc.exe process.  The following is the full command line on the server
 side:

 {{{
 pulseaudio -vvvvv --daemonize --high-priority --realtime --disallow-
 module-loading
            --resample-method=src-sinc-best-quality --no-cpu-limit -n
            -L "module-native-protocol-unix auth-anonymous=1"
            -L "module-native-protocol-tcp auth-ip-

            -L "module-simple-protocol-tcp port=4712 rate=44100
 format=s16le channels=2"
            -L "module-rescue-streams"
            -L "module-alsa-sink device=hw:1"
 }}}

 And here's the server startup log:

 And then a new connection from nc.exe is accepted and then nc.exe is
 killed:

 }}}

 Everything looks just OK, but pulseaudio process exits without any further
 log message.

 One the client side (i.e. Windows), I run the following command:

 {{{
 linco -B 16 -C 2 -R 44100 | nc 192.168.0.13 4712
 }}}

 linco.exe is at
 http://sourceforge.net/project/showfiles.php?group_id=99332&package_id=107331
 nc.exe is at http://joncraton.org/files/nc111nt.zip

 I am using PulseAudio 0.9.9 on Gentoo Linux.
