<div dir="ltr"><div style="font-family:arial,sans-serif;font-size:13px">My mythbackend process started crashing while sitting idle or during playback within the last week. It hasn't yet crashed while recording. The crash happens quite frequently, about every 45 minutes on average. This is the message from systemd when the crash happens:</div>

The client protocol message starts right after the backend starts, repeating every 5 or so seconds. I'm not sure if it is related or what client it is referring to. The frontend (on a different machine) is running v0.27, network protocol 77. The backend displays the protocol message even when the frontend isn't running.</div>
