[Serusers] rtpproxy mess

Hello, I am struggling with rtpproxy and I would like some help, because the documentation is rather scarce to be honest. I am running ser on an OpenBSD 3.3 box, with one internal interface (192.168.x.x) and a public interface (62.x.x.x). I am not sure wether I have to force rtpproxy to listen to a specific interface or not. I launch rtpproxy rather basically with ./rtpproxy -s /var/run/rtpproxy.sock Then I launch ser, it spawns some process and then run into race condition (see ps -aux below) Here is log file : Feb 2 15:34:28 cdg8-ser1 ser: WARNING: could not read from /dev/random (5) Feb 2 15:34:28 cdg8-ser1 ./ser[20970]: ERROR: send_rtpp_command: can't connect to RTP proxy Feb 2 15:34:28 cdg8-ser1 ./ser[32404]: ERROR: send_rtpp_command: can't connect to RTP proxy Feb 2 15:34:28 cdg8-ser1 ./ser[32404]: WARNING: rtpp_test: can't get version of the RTP proxy Feb 2 15:34:28 cdg8-ser1 ./ser[32404]: WARNING: rtpp_test: support for RTP proxyhas been disabled temporarily Feb 2 15:34:28 cdg8-ser1 ./ser[20970]: WARNING: rtpp_test: can't get version of the RTP proxy Feb 2 15:34:28 cdg8-ser1 ./ser[20970]: WARNING: rtpp_test: support for RTP proxyhas been disabled temporarily Feb 2 15:34:28 cdg8-ser1 ./ser[147]: ERROR: send_rtpp_command: can't connect to RTP proxy ...
