Docker postgres 12 和鳄梨酱错误 "incomplete message from client"

Question

我在 ubuntu18 上使用 docker 20.10.9，我用鳄梨酱和 guacd 1.3 与 postgres 12.3 组成项目，突然间容器或主机没有任何变化我的鳄梨酱停止工作，我有这些错误消息：

来自鳄梨酱团队，他们说“您需要检查您的 PostgreSQL 数据库服务器并确保它是健康的 - 出于某种原因拒绝来自鳄梨酱客户端系统的请求，这就是导致您看到的错误的原因。 “

我没有做任何更改，我可以登录到数据库并且容器是健康的这是 docker 网络：

我没有高 cpu \disk space 问题 \ 我在 psql 上检查了查询的运行ning 并且一切看起来都正常并且有一些查询运行从鳄梨酱那里得到很好的结果，有没有办法从 psql 获取更多信息以查看问题所在？或者我可以检查的任何其他想法？

也尝试重新启动所有 docker + docker 服务 + 重新启动服务器

谢谢。

通过

使用 clean db 启动 postgres 鳄梨酱解决了这个问题

mv data data_back
mkdir data

然后我重新启动了 docker compose

docker-compose down
docker-compose up -d

然后我制作了一个脚本，使用 API 请求将所有活动连接从我的常规数据库复制到鳄梨酱，它复制了所有 550 台机器。现在一切正常，似乎数据库损坏了。
