MOC is getting stuck after hours of playing of a streaming audio data

1. MOC is getting stuck after hours (I think more than six) of playing of a streaming audio data.
1.1. MOC itself is responding very slow.
1.2. The same sounds of a certain fraction of a second is repeating over and over.
1.2.1. A funny thing is that it keeps downloading the stream but it is, as mentioned, no longer playing the new collected data.
