I'm not sure what the deal is here but I'm watching the event logs over ssh and they stop working after a while. When I restart things work again. I've only paid attention to this over the course of days so I can't really define a "while". I can say it's not SSH because I'm also tailing nginx logs and such and they do not stop updating. It's just events.
