Module raop gets unloaded

[akecaca]

Hi,

When using Pulseaudio to play music on a remote Airport Express through the raop module, the module gets unloaded about 90 minutes after it has been launched. Before this point, it was running fine. Following lines can be found in the log (log-level=4):

...

I am using Pulseaudio (v 0.9.19) on a headless server (ubuntu server 9.10) running as a system daemon, with system.pa config as follows:

### Load several protocols
.ifexists module-esound-protocol-unix.so
load-module module-esound-protocol-unix
.endif
load-module module-native-protocol-unix auth-anonymous=1

### Allow access to airport express
load-module module-raop-discover
load-module module-raop-sink server=192.168.1.51 sink_name=raop
set-default-sink raop

### Automatically restore the volume of streams and devices
load-module module-stream-restore
load-module module-device-restore

### Automatically suspend sinks/sources that become idle for too long
load-module module-suspend-on-idle

I am using mpd as a client with following config:

audio_output {
        type            "pulse"
        name            "My Pulse Output"
        sink            "raop"
}

audio_output_format             "44100:16:2"
mixer_type                      "software"
