Unable to start grails war on tomcat6

I'm getting this in catalina.out when I try to deploy a grails application:

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.

Running Grails 2.0, Tomcat 6, Ubuntu 10.04. I haven't seen anything like this before, is this something I'm doing / can fix or something with how Tomcat is setup?

Are you running backgroundthread plugin by any chance? I have seen Tomcat fail to respond because of the plugin which does not give up the thread and prevents the server from shutting down correctly.

The real error will be in another log file in the logs directory. The thread leak messages are a concern, but that's an issue when shutting down. Your failure to startup is the problem and it's not described at all in what you've shown other than SEVERE: Context [/application] startup failed due to previous errors
