Do you know why we might be hitting it?

Maybe so - we are just hitting it a lot - we have one IP sending stuff
constantly - but we don't have anything like "keepalive" so it's
trying to make a new connection each time.
Is this what's killing it? Can we just raise ulimit and you think it'll fix it?
