我们在Windows Server 2008上运行GWT 2.5.1，Tomcat 7（最新版本），合理地更新IE，配置为通过SSL服务器网页。
用户可以运行网络应用程序，它将很乐意运行，直到用户关闭网络浏览器或从应用程序退出。
然而，在启动web-app后，tomcat主页立即无响应，在用户注销或重新启动浏览器后，web-app不响应。
恢复的唯一方法是重启tomcat。
如果我们在非SSL模式下运行tomcat，则没有问题。
修改
server.xml文件看起来非常标准，带有SSL连接器：
<Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true"
maxThreads="150" scheme="https" secure="true"
clientAuth="false" sslProtocol="TLS" keystoreFile="<file>" keystorePass="<pw>"/>
如果我们尝试转储线程，我们得到的是一个＆＃34;控制台CTRL + BREAK事件发出信号＆＃34;日志文件中的消息。
以下是Tomcat的部分日志。正如您所看到的，一旦我们启动了网络应用程序，一切都会完全沉默。
标准输出

设法获得完整的日志，包括关闭，我们现在在catalina / stderr日志中获得以下内容。我们没有在工作系统中获得此输出。
这强烈暗示由于某种原因，线程[Thread-3]和 [MultiThreadedHttpConnectionManager清理]正在挂起。任何人都可以建议我应该在哪里寻找原因吗？
