"Too many open files" when attempting Chromaprint

[danb35]

I'm running Beets 2.2.0 under Ubuntu 22.04, installed using pip with a few plugins including Chromaprint. I believe I have all the dependencies installed--fpcalc is present and runs, GStreamer is installed following its docs (https://gstreamer.freedesktop.org/documentation/installing/on-linux.html#install-gstreamer-on-ubuntu-or-debian), ffmpeg is present. My config file is below:

directory: /mnt/media/music_new
library: ~/.config/beets/library.db

plugins: chroma fetchart embedart duplicates web

duplicates:
  tiebreak:
    items: [bitrate]

Beets version:

dan@beets:~$ beet version
beets version 2.2.0
Python version 3.10.12
plugins: chroma, duplicates, embedart, fetchart, web

When I try to import my music using beet -v import /mnt/media/Music2, I get this output:

Sending event: import_task_created
chroma: fingerprinting of b'/mnt/media/Music2/_ When I See The King Of Kings.mp3' failed: audio could not be decoded
chroma: fingerprinting of b'/mnt/media/Music2/_ When The Roll Is Called Up Yon (1).mp3' failed: audio could not be decoded

fpcalc on that file succeeds:

Where should I be looking to track this down?
