java.net.SocketException：没有可用的缓冲区空间（已达到最大连接数？）：（添加 netstat -a）
我正在使用 tomcat 7.x ，当我在一段时间后启动服务器时，我收到以下错误。
Sep 17, 2011 4:46:53 PM org.apache.catalina.startup.Catalina stopServer
SEVERE: Catalina.stop:

之后我检查了所有泄漏的连接和其他资源，我的应用程序完全没问题。
但是当这个错误出现时，我必须重新启动计算机。即使重新启动服务器后，这也无法恢复。
我在这个问题出现之前和问题出现之后粘贴我的netstat -a。

谁能帮我理解这个 netstat 吗？现在这个问题出现得非常频繁。
I am using tomcat 7.x , when I am starting my server after some time I am getting following error.
Sep 17, 2011 4:46:53 PM org.apache.catalina.startup.Catalina stopServer

after this I checked all my leaked connection and other resources, my application is completely fine.
but when this error comes, I have to restart my computer. Even after restart the server this is not recoverable.
I am pasting my netstat -a, before this issue comes and after the issue comes.
Before.

听起来您的交换空间不足。如果重新启动应用程序没有帮助，则表明另一个应用程序正在使用内存。当您停止应用程序时，它会释放应用程序使用的所有资源。即重新启动了错误的应用程序。
发生这种情况时，您能否确定退出 tomcat 后有多少可用内存？如果低的话，内存消耗最大的是什么？
能不能增加机器的交换空间，或者更好的增加机器的物理内存？
你能减少其他应用程序的内存消耗吗（或者tomcat，如果它被证明是问题所在，但听起来不像）
Sounds like you are out of swap space. If it restarting the application doesn't help, it suggests another application is using the memory. When you stop an application its free all the resources that application uses. i.e. the wrong application was restarted.
Can you determine how much free memory is available after you exit tomcat when this has happened? If it is low, what is the biggest consumer of memory?
Can you increase the swap space of the machine, or better increase the physical memory of the machine?
Can you reduce memory consumption of your other applications (or tomcat if it proves to be the issue, but it doesn't sound like it)
