somtimes streaming breaking and not working later

[Diz]

I'm trying extraction audio and making audio stream http://IP:Port/filename.mp3

cvlc -vvv --network-caching 4000 "http://178.162.218.87:8081/liveg/tnt.st ... sAuthSign=" --sout "#transcode{vcodec=none,acodec=mp3,ab=128,channels=2,samplerate=44100}:http{dst=192.168.1.7:8081/stream.mp3}"

On other machine i starting Vlc and listen it in http://192.168.1.7:8081/stream.mp3
In one moment sometime it's working sometime not.
I need restart or server part or client part.
May be need i set some command line options?
