Can't say for sure, especially on the first one. In 'Nix, I'd start looking to see what else was taking 443.
The second is what it says ... PHP wasn't compiled to operate with an SSL-aware Apache. A recompilation with the correct option is the only real solution. I would offer that on lower trafficked servers, I've not seen this actually cause a crash, but it must be possible, or they wouldn't be warning us, right?
