当负载增加时，我的群集中的某些JBoss节点拒绝新连接。但是，当我查看这些节点的CPU /内存使用情况时，它们处于最低级别，不超过10％的CPU使用率和60％的内存使用率。我不明白还有什么导致连接被拒绝。在某些情况下，连接在负载平衡器本身进入任何节点之前都会被拒绝。也没有网络延迟。整个环境都在局域网内。以下是错误消息。
Unable to connect to server. Error attempting to connect a socket to a remote address and port. Typically, the server is down or cannot open more sockets on its system. If the error detail is "java.net.ConnectException: Connection timed out: connect" for all requests, it typically means that the Load Generator is using an inappropriate network interface. Details: java.net.ConnectException: Connection refused: connect
