I have rather a frustrating issue in that I'm getting errors appearing in the logs relating to queries that cannot run or complete, which is odd as the pages are normally fine, further investigation shows the error:

Caused by: java.net.SocketException: No buffer space available (maximum connections reached?): connect

I am running Tomcat 6 on Windows Server 2008 R2 Datacentre (1 CPU), MySQL 5.0.85 with mysql-connector-java-5.1.25.

I've not experienced any pages throw errors when I access our websites, but some users must be experiencing an issue, hence the error logs. Needle in a haystack pops to mind, if anyone could please shed some light as to a resolution it would be much appreciated :-)

我将所有项目迁移到 Tomcat 7.0.42 并且我的错误消失了，我们的网站更加稳定且速度稍快，我们使用的内存更少，CPU 使用率也更好。

假设您的 CPU 中有多个内核，这通常是由于 Windows Server 2008 R2 中的一个错误 (ID 2577795)。Microsoft提供了一个修补程序。
