启动服务时RabbitMQ虚拟主机报错

Question

我已经运行了几个月的 RabbitMQ 服务器。今天早上我无法连接到它，我的应用程序超时并且管理客户端没有响应。重新启动了机器。应用程序仍然超时。我可以登录到管理客户端，但看到以下消息:

Virtual host / experienced an error on node rabbit@MQT01 and may be inaccessible

我所有的队列都在那里，但看不到任何交流。

我希望有人能帮我弄清楚发生了什么。我查看了日志，但找不到任何好的提示。

这是日志的一部分:

Answer 1

我想通了是怎么回事。我团队中的某个人(我)正在创建与 RabbitMQ 的空前数量的连接。对于每个连接，都会为一个或多个文件创建一个文件处理程序，不确定是哪个。操作系统(在我的例子中是 Windows)有一个文件处理程序限制，不确定这个限制是什么，但是当达到时，会抛出一个错误。这损坏了虚拟主机 (/)，我不得不删除它并重新创建它。好在这不是生产，因为那样所有的消息都会消失。
编辑(2020 年 6 月):
可能有一个解决方案，因此它不会再次发生。虚拟主机可以限制它们允许的连接数。这样 Windows 就不会在许多文件句柄上出错。查看管理门户 -> 管理 -> 限制，将最大连接数设置为您认为适合您的设置的数字。
