Steven, In your config, instead of <root>, try <asyncRoot>. You need the disruptor jar on the classpath. This will result in events being flushed to disk immediately, but in an efficient way: in batches, not one by one.
I need to take a look at the behavior on Tomcat shutdown. There is a shutdown hook that should flush remaining events, but perhaps you found a bug. Can you try <asyncRoot> and let me know if that resolves the issue?
