WSO2 ESB 有时会丢失与 Websphere MQ 的 JMS 连接。建立新连接至少持续 1-2 秒。这会导致使用此连接的代理服务超时。
WSO2 ESB 4.8.1， IBM Webpshere MQ 7.0.1.12
奇怪的堆栈跟踪：

您在堆栈跟踪中看到的关键错误是：
由以下原因引起：java.net.Socket异常：无法识别的 Windows 套接字错误：0：recv 失败 at java.net.SocketInputStream.socketRead0（Native Method） at java.net.SocketInputStream.read（SocketInputStream.java：152） at java.net.SocketInputStream.read（SocketInputStream.java：122）
这表明JVM通过Windows套接字收到了它没有预料到的东西。看起来您使用的是Oracle JVM，而不是MQ附带的IBMJVM。
我建议您尝试升级到较新的JVM（如果有的话）。请注意，您使用的 MQ 7.0.1 客户机支持 Java 5 和 Java 6。如果要使用 Java 7，则需要使用 7.1 或更高版本的 MQ 客户端。所有 IBM MQ 客户机均可通过 MQC 支持包免费获得：
MQ 7.1 客户端：http://www-01.ibm.com/support/docview.wss?uid=swg24031412
MQ 7.5 客户端：http://www-01.ibm.com/support/docview.wss?uid=swg24032744
MQ 8.0 客户机：http://www-01.ibm.com/support/docview.wss?uid=swg24037500
如果 Oracle 没有更新的 JVM，我建议与他们一起开一张支持票，以便他们进行调查。
