当我尝试部署 grails 应用程序时，我在 catalina.out 中得到了这个：

Feb 9, 2012 10:32:25 PM org.apache.catalina.core.StandardContext start
SEVERE: Error listenerStart
Feb 9, 2012 10:32:25 PM org.apache.catalina.core.StandardContext start
SEVERE: Context [/application] startup failed due to previous errors
Feb 9, 2012 10:32:25 PM org.apache.catalina.loader.WebappClassLoader clearThreadLocalMap
SEVERE: A web application created a ThreadLocal with key of type [org.springframework.core.NamedThreadLocal] (value [Transaction synchronizations]) and a value of type [null] (value [null]) but failed to remove it when the web application was stopped. To prevent a memory leak, the ThreadLocal has been forcibly removed.

To prevent a memory leak, the ThreadLocal has been forcibly removed.

运行 Grails 2.0、Tomcat 6、Ubuntu 10.04。我以前从未见过这样的事情，这是我正在做/可以修复的事情还是与 Tomcat 的设置方式有关？

【解决方案1】：

真正的错误将在日志目录中的另一个日志文件中。线程泄漏消息是一个问题，但在关闭时这是一个问题。您无法启动是问题所在，除了SEVERE: Context [/application] startup failed due to previous errors

【解决方案2】：

您是否正在运行 backgroundthread 插件？我看到Tomcat没有响应是因为插件没有放弃线程并阻止服务器正确关闭。
