这必须与负载有关，但没有警告或错误 SimpleBrokerMessageHandler - 处理 DISCONNECT 开始发生在一定数量的同时连接之上。我已经尝试过跟踪日志记录，但我仍然看不到会话关闭的原因。但是，即使少一个客户端连接，测试也能顺利进行。

这是一个非常标准的 spring framework 4 websocket STOMP 应用程序，除了我为入站、出站和代理通道配置了 reactor-spring RingBufferAsyncTaskExecutor。我使用的是简单代理，因为目前我总是只回复 websocket 会话的连接客户端，即：org.springframework.messaging.simp.broker.SimpleBrokerMessageHandler - 广播到 1 个会话。

这是日志的一部分，一切看起来都很正常，然后所有 websocket 会话都断开连接，我的客户端自动尝试重新连接，但他们无法连接。是否在某个地方设置了限制，或者有更多春季经验的人知道问题出在哪里？
