我在 docker 容器中运行 ejabberd。很长一段时间内一切正常，但今天我发现一个小时左右后 ejabberd 崩溃了。这是 crash.log 文件的重要部分。

......

基于崩溃错误日志似乎与日志轮换有关。

Cannot rename disk_log file",latest_log,"/opt/ejabberd/database/ejabberd@localhost/PREVIOUS.LOG

奇怪的是，每当我重新启动容器时一切正常，我显然可以看到/opt/ejabberd/database/ejabberd@localhost/包含所有文件的目录以及LATEST.LOG文件。一个小时左右后，它崩溃了，然后里面的所有东西/opt/ejabberd/database/ejabberd@localhost/都消失了，即使ejabberd@localhost目录也被删除了。

如果我进入容器内部，我将无法再次创建目录或目录中的任何其他文件/opt/ejabberd/database/。

$mkdir -p /opt/ejabberd/database/ejabberd@localhost

mkdir: cannot create directory ‘/opt/ejabberd/database/ejabberd@localhost’: No such file or directory

似乎不是权限问题

$ls -lh /opt/ejabberd/

不得不说我以前没有这个，有没有人在使用 ejabberd 的 docker 容器中经历过类似的事情？有什么想法会导致这个奇怪的错误吗？

提前致谢
