What's your basic architecture? Are you multi-threaded? Do you call epoll_wait with a timeout? Do you use one-shot events or edge-triggering? If neither edge-triggered nor level-triggered, you cannot call EPOLL until you have finished handling all the events you got on the previous pass. EPOLL should be a drop-in replacement for 'select' with no issues. It's only when you try to use its special features that you can get into trouble. I'd go over the possible mistakes for when you want to wait for read or write events, but it the same as when you want a socket in the read or write set for 'select'. So if it works with 'select', that probably isn't your problem. Are you sure it's an OpenSSL-related issue at all? Can you use EPOLL without OpenSSL without problems? (Do you know what you're doing? Do you just not know how to use EPOLL?)
