Why did you add the "_0_RELEASE" at the end of your src-all, ports-all and doc-all
tags?
FWIW this is what I use for 5.1 Release and never had any problems except I
occasionally change the mirror name if the connection seems bad with one in particular:
*default host=cvsup10.FreeBSD.org
*default
can someone take a look at my cvsupfile and see if it's alright:
---
*default host=cvsup10.us.FreeBSD.org
*default base=/usr
*default prefix=/usr
*default release=cvs
*default tag=RELENG_5_1
*default delete use-rel-suffix
src-all tag=RELENG_5_1_0_RELEASE
