体验＆＃34;无法连接到rabbitmq服务器（连接超时）＆＃34;某时

Question

这个rabbitmq服务器有大约1,000 msg /秒 在nodejs和php中编写了多个微服务。 但是对于php应用程序，我们有时会遇到问题，这个警告

stream_socket_client(): unable to connect to tcp://RABBITSERVER:5672 (Connection timed out)

每天几次。但我预计它将为零。

我应该从哪里开始调试？

在rabbitmq startup_log中，它会被跟踪日志

淹没

我使用的是rabbitmq服务器版本3.5.4 我服务器中的erlang是R16B03-1

我可以调整任何调整吗？应该在服务器或rabbitmq服务中进行调整。

请告知。
