我们有几个Spring出站SOAP WebServices客户端（与外部WS交谈）。我们使用Spring Integration Gateway与他们交谈。
使用的版本：
Spring Integration version - 4.0.4.RELEASE
Spring version - 4.1.6.RELEASE
Spring WS - 2.2.4
Apache http client - 4.5.1
当有效载荷为几kbs时，一切正常。但是当我们有一个稍微大一点的有效载荷（说700KB，我知道不是很大）时，处理就会卡住。线程转储提供以下StackTrace。这在Weblogic（12C）和Apache Tomcat中都会发生，但仅在Linux上发生。
之前有人遇到过这个问题吗？ Spring Integration / Gateway中是否有一些配置可以设置writebuffer大小？

更新 我修改了HttpClient的DefaultSocketConfig（自定义）以将setSndBufSize包含到一个大的on。仍然没有效果！
在运行netstat -ant | grep 443时，tcp状态为CLOSE_WAIT（有时是LAST_ACK）并永远保持挂起状态。

在我看来，缓冲区已满 - 服务器读取速度不够快或网络速度慢 - 您需要运行网络监视器，例如wireshark
