Since CVS updates are not atomic, it's hard to see how mirroring could be, unless you did something like disallow updates, mirror, allow updates. I suspect such a cure would be worse than the disease. This is such a rare event that I don't think it's worth the trouble. Buildfarm members are doing 200 builds a day or more, and I can't recall having seen this before. cheers andrew ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
