Looking at the code again (it's written long ago), yes you're right, the polling would stop at 60s if there's no data available. So I guess this is quite expected behaviour. However instead of setting shutdown_timeout, I think I would probably need to make the application know that the server is shutting down, and stop right there instead of waiting for full 60 seconds. Not sure if I could do this without talking to yahns directly... >> I looked around the code, which should be: >> >> def dropping(fdmap) >> if drop_acceptors[0] || fdmap.size > 0 >> timeout = @shutdown_expire < Yahns.now ? -1 : @shutdown_timeout >> fdmap.desperate_expire(timeout) >> true >> else >> false >> end >> end >> >> While Yahns.now would get growing, I don't really understand why >> it's written like this?
