So I'm using the Basic Sourdough recipe in the BBA.  I fed the starter two nights ago, made the dough last night and got a good first ferment out of it.  The dough doubled in 4 hours.  I knocked the dough down and shaped it into baguettes and boules, covered them with plastic wrap, and stuck them in the fridge overnight.
I took them out this morning and left them in my 75-80 degree kitchen.  After 6 hours, they hadn't risen at all.  They were still flat as pancakes.
When I baked them, I got a fair oven spring, but not enough to offset the lack of a secondary rise.  The interior is dense and chewy.
I did the same thing with some sourdough rye loaves, and got a fairly good second rise out of them.
Any suggestions?
Thanks,
-Joe
        

I just came across some information on Peter Reinhart's blog regarding getting sourdough starters up and running. I thought I would pass it on for those who haven't seen it yet.
