Question

我们有一个独立的Chef服务器安装（v 12.1.2）。它已经运行好几个月，但最近它已经开始每天几次崩溃。看看日志，它看起来像是＆＃34; opscode-erchef＆＃34;服务每天都会崩溃几次。这来自opscode-erchef崩溃日志：

Rettarting opscode-erchef followed by opscode-expander service brings it back again.

有谁可以告诉，在什么情况下opscode-erchef服务会崩溃？当发生这种情况时，我不会看到CPU或内存上的任何压力。所以服务器资源似乎不是问题。

谢谢！

错误与RabbitMQ和工人有关;尝试增加RabbitMQ可用的连接数量或调整超时或增加连接。

rabbitmq['rabbit_mgmt_http_max_count']

rabbitmq-management插件使用的HTTP连接池的最大工作计数。默认值：100。

rabbitmq['rabbit_mgmt_timeout']

rabbitmq-management插件使用的HTTP连接池的超时。默认值：30000。
