Do you use the (experimental) feature “Convert video while recording” in your DVR configuration? I ask because there was a new capability to use hardware acceleration for this added in 1.41.0.9057 that could have affected stability.
If you do use this feature, I’d recommend turning it off for the time being (in conjunction with the latest beta server version). While it can work well, it does add another potential point of failure in the recording pipeline (transcoding). In my experience it can be a little brittle if there is any video breakup due to marginal signal quality.
