Question

我正在对RabbitMQ使用MassTransit。在大多数情况下，它运行良好，但是一段时间后，消费者开始抛出S-FAULT警告：

MassTransit.Messages Warning: 0 : S-FAULT rabbitmq://<redacted>/iemr_ExistingRowCheck 62560000-56b4-0050-b40b-08d69864ff75 ieMR.BulkCopy.MissingRowImport.Queues.ExistingRowCheck

我可以忽略这些警告吗？

我正在使用MassTransit 5.3.1.0，并在Erlang 20.3上针对RabbitMq 3.7.5匹配了MassTransit.RabbitMqTransport。

Answer 1

我通常将服务器上的网络错误扔进位桶中。

这意味着有状态防火墙断开了（死）连接，或者另一端的IP地址无法以您的主机OS可以快速检测到的方式到达。

感谢您查看RabbitMQ日志的建议。

日志中充满了类似以下内容的行：

2019-02-23 11:01:35.254 [info] <0.280.0> vm_memory_high_watermark set. Memory used:1724121088 allowed:1717798502
2019-02-23 11:01:35.254 [warning] <0.278.0> memory resource limit alarm set on node 'rabbit@THHS-D-RABTMQ01'.

**********************************************************
*** Publishers will be blocked until this alarm clears ***
**********************************************************
2019-02-23 11:02:22.596 [info] <0.280.0> vm_memory_high_watermark clear. Memory used:1714683904 allowed:1717798502

增加rabbitmq.conf中的内存高水位标记似乎可以解决问题：

vm_memory_high_watermark.relative = 0.8

我将要求服务器团队在星期一增加这台计算机上的内存。

建立的连接已被您主机中的软件中止
