FFMPEG get stuck when transcoding too many FLAC audios

I'm currently using Editly for create some videos from code, but there are some bugs with ffmpeg(latest).

Nothing returns after hours processing(460 audios files during test), I already tried with flac, aac, libshine and libmp3lame encoders, already tried a different a ffmpeg version(static).

From the editly code, I already changed the ffmpeg query, slicing in chunks(75), the results were:

• 0, 75 ok
• 0, 80 stuck
• 75, 150 ok
• 150, 225 ok
• 225, 300 stuck
• 300, 375 ok
• 375, 450 ok

Stuck screen(directly from terminal):

Editly code for generating FFMPEG query:

    let inStream = '[0:a]';    const filterGraph = clipAudio.slice(0, -1).map(({ transition }, i) => {      const outStream = `[concat${i}]`;      const epsilon = 0.0001; // If duration is 0, ffmpeg seems to default to 1 sec instead, hence epsilon.      let ret = `${inStream}[${i + 1}:a]acrossfade=d=${Math.max(epsilon, transition.duration)}:c1=${transition.audioOutCurve || 'tri'}:c2=${transition.audioInCurve || 'tri'}`;      inStream = outStream;      if (i < clipAudio.length - 2) ret += outStream;      return ret;    }).join(',');    const args = [      ...getFfmpegCommonArgs({ enableFfmpegLog }),      ...(flatMap(clipAudio, ({ path }) => ['-i', path])),'-filter_complex',      filterGraph,'-c', 'flac','-y',      outPath,    ];    await execa(ffmpegPath, args);

FFMPEG query structure:

ffmpeg -i /editly-tmp-.../clip000-audio.flac -i /editly-tmp-.../clip226-audio.flac -i ... -filter_complex [0:a][1:a]acrossfade=d=1:c1=tri:c2=tri[concat0],[concat0][2:a]acrossfade=d=0.425:c1=tri:c2=tri[concat1],[concat1][3:a]acrossfade=d=0.425:c1=tri:c2=tri[concat2],... -c flac -y /editly-tmp-.../audio-concat-3.mp3

Sorry my poor english :P

Change Codecs, FFMPEG version, node version, slice the files in chunks, change SO(worked in Windows).
