RabbitMQ通用服务器rabbit_disk_monitor终止/ eheap_alloc:无法分配229520字节内存(类型为"old_heap")
提问于 2015-07-21 16:12:32
RabbitMQ坠毁了。RabbitMQ正常工作了很多天(10-15天)。我不明白它为什么坠毁了。
我在Erlang17.0上使用RabbitMQ 3.4.0
erlang已经为崩溃创建了转储文件。这表明
eheap_alloc: Cannot allocate 229520 bytes of memory (of type "old_heap").还请注意，rabbitmq发布-订阅消息负载非常低。(最大值:1-2条消息/秒).And RabbitMQ消息是在它出现时被处理的，所以RabbitMQ几乎一直都是空的。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日志如下所示。
