液体肥皂无法将数据写入主机:写入() 错误中的管道断开

Question

我的 liquidsoap 音频流刚刚开始停止播放，每隔几个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()!

它似乎很快就修复了自己，我可以重新开始播放，但中断很烦人。

我正在使用的liquidsoap脚本非常基本，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。

我不确定为什么它开始这样做，因为它之前已经完美运行了很长时间，而且我没有进行任何更改。

任何建议或帮助非常感谢，因为我对液体肥皂的理解是非常基本的。

谢谢。

万一其他人在我的情况下遇到此错误消息，问题不在于液体肥皂本身，而在于 API 请求花费的时间太长并且导致调度失败。
