-CURRENT is called CURRENT because it reflects the CURRENT development efforts and their CURRENT state. Of course it may crash. When it stops crashing, it's going to be released and that's how it will be turned into a RELEASE.

There is literally (and I'm using the word in its proper sense, not as a hyperbola) no way you end up with FreeBSD on a server without knowing this. No one just installed it "by mistake" in a production environment or mistook it for a STABLE version.
