RabbitMQ 崩溃了。RabbitMQ 已正常工作很多天(10-15 天)。我不明白为什么它崩溃了。

<小时/>

我在 Erlang 17.0 上使用 RabbitMQ 3.4.0

<小时/>

erlang 已为崩溃创建转储文件。其中显示

eheap_alloc: Cannot allocate 229520 bytes of memory (of type "old_heap").
<小时/>

另请注意,rabbitmq 发布-订阅消息负载非常低。 (最大:1-2 条消息/秒)。并且 RabbitMQ 消息在到达时进行处理,因此 RabbitMQ 几乎一直是空的。磁盘空间和内存也足够。

More system info:
Limiting to approx 8092 file handles (7280 sockets)
Memory limit set to 6553MB of 16383MB total.
Disk free limit set to 50MB.

RabbitMQ 日志如下。

最佳答案

从错误信息来看,由于系统限制,rabbitmq无法打开更多文件。您可以将最大打开文件数设置为较高值以避免出现此问题。
