旧环境（Ubuntu18.04+Docker19.03.13）下Python3.10+的multiprocessing.Manager异常问题求助

我遇到了一个棘手的问题：需要在装有Docker 19.03.13的Ubuntu18.04主机上部署Python应用，但目前这两者都没法更新，只能在现有环境下解决问题。

当我尝试运行应用时，它总是因为多进程相关的异常崩溃。我把问题简化成了两行测试代码来复现：

from multiprocessing import Manager
Manager().dict()

我试过不同版本的Python3官方镜像，但所有测试过的3.10+版本都抛出了两种异常之一：

第一种是连接重置错误：

ConnectionResetError: [Errno 104] Connection reset by peer

第二种是文件找不到错误：

FileNotFoundError: [Errno 2] No such file or directory

    s.connect(address) FileNotFoundError: [Errno 2] No such file or directory

我的测试方式是通过以下命令启动Docker容器，然后在交互式解释器中运行上述两行代码：

docker run -it --entrypoint=/bin/bash python:VERSION

我试过的大多数Python版本都出现了上述异常，只有python:3.8.2能够正常运行。

另外，在其他装有较新OS和Docker的机器上，所有Python版本都能正常工作。

所以我的问题是：在不更新主机OS和Docker的前提下，如何让Python3.10+在这个旧环境中正常运行？
