Ryan If this is so easily replicated for you it should be trivially found and fixed most likely.
Please share, for each node in your cluster, both a thread dump and heap dump within 30 mins of startup and again after 24 hours. This will allow us to see the delta and if there appears to be any sort of leak. If you cannot share these then you can do that analysis and share the results. Nobody should have to restart nodes to keep things healthy.
