Question

我们的群集由HA中的3个磁盘节点组成。所有节点均为4CPUx26Gig RAM。我们使用带有Erlang 17.3的RabbitMQ 3.6.5。唯一启用的插件是管理UI插件。

问题在于，通常在3小时的时间内，其中一个服务器（通常是队列最多的服务器）会开始逐渐占用内存，直到服务器崩溃。这种情况每天都会发生，我们认为没有任何理由在日志中发生这种情况。

附件是服务器从21GB内存堆积起来的日志，此时，当查看管理UI中的概述窗格时 - 它显示仅使用2GB。当发生这种情况时，我们通常有~400个连接，有~470个通道，16个交换，54个队列和~300个消费者。其中一个队列是启用TTL，4个是优先级队列，所有队列都是持久的。

服务重启后，一切都恢复正常。

关于导致它的原因的任何想法/我们应该如何进行调试？排除已知问题的清单？
