Liquidsoap 无法将数据写入主机：Broken pipe in write() 错误

Question

我的 liquidsoap 音频流刚刚开始停止播放，每隔几次请求就会出现此错误消息。

Error while sending data: could not write data to host: Broken pipe in write()!

它似乎很快就会自行修复，我可以重新开始播放，但中断很烦人。

我使用的 liquidsoap 脚本非常基础，可以从数据库中提取一些歌曲。

这是脚本。

def apply_metadata(m) =
  title = m["title"]
  artist = m["artist"]
  log("Now playing: #{title} by #{artist}")
end

def apply_track(m) =
  get_process_lines("curl http://localhost/api/v1/liquidsoap/playing")
  log("actually playing")
end

def get_request() =
  uri = list.hd(default="",get_process_lines("curl http://localhost/api/v1/liquidsoap/next"))
  request.create(uri)
end

def my_safe(s) =
  security = sine()
  fallback(track_sensitive=false,[s,security])
end

s = request.dynamic(id="s",timeout=60.0,get_request)
s = on_metadata(apply_metadata,s)
s = on_track(apply_track,s)
s = crossfade(s)
s = my_safe(s)

# We output the stream to an icecast
# server, in ogg/vorbis format.
output.icecast(
  %mp3(id3v2=true,bitrate=128,samplerate=44100),
  host = "localhost",
  port = 8000,
  mount = "ogr",
  s
)

这是液体肥皂日志。

我不确定它为什么开始这样做，因为它之前很长一段时间都运行良好，而且我没有做任何更改。

非常感谢任何建议或帮助，因为我对液体皂的理解非常基础。

谢谢。

万一其他人在我的案例中遇到此错误消息，问题不在于液体肥皂本身，而是 API 请求花费的时间太长，导致计划失败。
