Mediastream goes defunct

Question

I am running my donnet framework based application using mono in Linux Ubuntu. My application uses linphone's mediastream command to open the RTP socket and hook the audio device. I am using the following mediastream command to call from my application:

mediastream (arguments......)

Every thing is working fine but when i am trying to kill the mediastream using the killall command, it goes defunct. I am giving the following command from my application:

killall mediastream

What I am doing wrong? How can I handle those defunct processes?

Answer 1

Linphone's mediastream require CTRL+C (SIGINT) to close properly and killall default signal is SIGTERM. So you can try SIGINT signal in killall command as follows:

killall -SIGINT mediastream

or

killall -2 mediastream
