If server detects timestamp errors in published stream (due to packet loss, for example), the stream is automatically nomalized by adding skipped frames. Sometimes, this can lead to a dramatic FPS and bitrate inscrease, audio/video synchronization loss and, therefore, the stream playback from server becomes impossible.
To prevent unneeded normalizing, since build 5.2.745 the parameter is added to set a maximum timestamp consecutive errors count. When the threshold is reached, normalizing is stopped with fallback to original timestamps. By default, the parameter is set to 90 consecutive errors
