我的 MySQL 错误日志有问题，目前主要由“mbind：不允许操作”行组成（见下文）。为什么会发生这种情况？我该如何修复？
困扰我的是“大部分”部分。正如您在下面看到的，并非所有行都是“mbind：不允许操作”。我怀疑 MySQL 查询错误应该代替该行，但出于某种原因，它们无法写入文件中。
MySQL 本身是一个 Docker 容器，其中日志文件通过以下方式进行卷管理：
volumes:
- ./mysql/log:/var/log/mysql
有趣的是：
- “docker logs mysql_container”没有显示任何内容......
- 位于同一卷文件夹中的 slow.log 完全正常，并且包含真正的慢速日志行，根本没有“mbind：操作不允许”！
- 与 slow.log 转到 general.log 一样 — 这里也没有问题
有什么想法吗？提前谢谢您。

PS MySQL 启动并运行良好，没有问题。只是这个 error.log 一直困扰着我，让我看不到实际的错误。
