I can not find the cause. Because of what falls media portal. I asked here:It works (I let it go 20 mins) unless you hit pause (which I had been warned about) I didn't know you could pause streams anyway ... maybe temporarily disable pause to avoid this. But generally, an improvement. Thanks!
It is necessary to me to try to analyze the log file when it is time. And I have not recently falls during the pause, but does not play after that.
