Even when you build world/kernel with -j4 there should be an error message. What is it? If you can't find it build without -j4. If it still fails post the error here or on the stable mailing list. I build world and kernel (stable/13 and main) for amd64, armv7 and arm64 with -j4 and have no issues. -- Herbert
