An email from Danstar:
"Thanks for your inquiry. Indeed we are asking retailers to suspend sales of batch number 1080961099V and to return the inventory to us, and we will be posting something to homebrew forums in the coming days as well. While our tests of retained samples of this batch are fermenting properly, there are a lot of people reporting difficulties with this batch via forums, and we have received inquiries from a few people that have contacted us directly. We feel it is better to withdraw this batch from the market and assess the nature of the issue rather than risk brewers getting disappointing results.
Thanks again, and let me know if you have any more questions."

Crap! It looks like I have some of this lot. Time to call my LHBS.
