"use FreeBSD STABLE branch if you are going use it as a production server"

No.

For a production server, use RELENG_4_9, the release branch. To get a little more confusing, the RELENG_4 branch is the STABLE development branch.

CURRENT is exacrly that, it's current source and may or may not be stable or useable. STABLE really isn't guaranteed to be "stable", it is still development and isn't for production use. RELEASE is the "stable" release version.

Here's the CVS tags: http://www.freebsd.org/doc/en_US.ISO8859-1/books/h andbook/cvs-tags.html
