I've recently experienced an occasional stall through the shell to FWS and after some searching I believe it may be related to a recent change in the network card driver with the last kernel upgrade. We'll be trying a few things over the next two days and then we'll be upgrading to the latest stable release to see if that fixes it. Seeing as though the server has more then enough power and the loads been light I believe this is the problem. I'll bump this thread up once the changes are done to see if you notice any changes as well.
Until then if you notice it stall try to reload or open the page in a new window and it should be sent rather quickly. There doesn't seem to be a pattern to the stalls but I can confirm they do exist.
