django - Django中随机发生的运行时错误死锁

Question

在 Python 3.7.9 中运行 Django。我正在使用 channel ，因此使用了达芙妮，但即使我使用 gunicorn 也获得了相同的结果。
下面的错误是随机出现的。

ERROR        2021-07-12 11:55:07,478 HTTP GET /static/customer/assets/js/jquery.min.js 500 [0.71, 127.0.0.1:55466]
ERROR        2021-07-12 11:55:07,479 Exception inside application: Single thread executor already being used, would deadlock
Traceback (most recent call last):
  File "/home/x/.pyenv/versions/3.7.9/lib/python3.7/site-packages/channels/http.py", line 192, in __call__
    await self.handle(body_stream)
  File "/home/x/.pyenv/versions/3.7.9/lib/python3.7/site-packages/asgiref/sync.py", line 410, in __call__
    "Single thread executor already being used, would deadlock"
RuntimeError: Single thread executor already being used, would deadlock

我认为这个错误与死锁关系不大，但有时它们会同时出现。

 ERROR        2021-07-12 11:55:07,478 HTTP GET
/static/customer/assets/js/jquery.min.js 500 [0.71, 127.0.0.1:55466]

我该如何解决这个问题？
