Tomcat的請求負載問題「連接被拒絕」

我在Tomcat上7.50的應用程序，在單一的請求，但在許多simultanious請求（〜1200）我得到正常工作：Tomcat的請求負載問題「連接被拒絕」

我的server.xml中的連接器：

<Connector port="9080" protocol="HTTP/1.1" 
connectionTimeout="60000" 
redirectPort="8443" keepAliveTimeout = "-1" 
maxThreads="150" acceptCount="1500"/>

這很好，如果一些請求將被拒絕，並會在接下來的迭代中解決，但只有幾（〜5）越來越服務器之前成功給我那些messaggs

鐠問題實際上是記憶問題。通過刪除-Xmx屬性釋放某些堆棧內存後，問題得以解決
