此问题是windows的bug，唯一解决问题的方法就是reboot，然后给系统打补丁，The problem was fixed with Microsoft's patch: "Kernel sockets leak on a multiprocessor computer that is running Windows Server 2008 R2 or Windows 7" (http://support.microsoft.com/kb/2577795) (ie. Buddy Casino's answer (see below)).

Tomcat is running a webapp under Windows. After a few days (under very low load), the exception mentioned in the title starts to appear in the logs, no new connections can be established from that point on, the only fix is then to reboot the server.
回复1：
The reason we got this error is a bug in Windows Server 2008 R2 / Windows 7. The kernel leaks loopback sockets due to a race condition on machines with more than one core, this patch fixes the issue: http://support.microsoft.com/kb/2577795
回复2：
I was running Alfresco Community 4.0d on Windows 7 64 bit and had the same symptoms and errors.

Another observation I'd like to add is that Windows connections (Internet Explorer, Remote Desktop etc) would work again about 5-10 mins after the Alfresco services were shutdown.
Alfresco is an excellent product and I was afraid I would have to scrap it. Fortunately stackoverflow came to the rescue !
