Tomcat access logs - are failed requests included?

We have a RESTful web service (Java, hosted in Tomcat on Ubuntu on Amazon EC2). From time to time it fails (not every week). When it fails, Java CPU consumption goes to 100% and it takes all available memory. It does not finish by itself. I have to restart the server.

There is nothing suspicious in Tomcat access logs. I guess one of our users could submit a very "heavy" request which brought the server down. Is it possible this request is not in Tomcat logs since it never finished?
