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-acl=192.168.0.0/16;127.0.0.0/8"
-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.
