Hi David, I've seen something similar. Unfortunatelly, I couldn't find the reason. I'm using the MySQLdb adapter and have a very strong suspision that this is DB related. But, it could really be some rare race condition I'm seeing. And I'm using a really old version of Webware, what might be a problem as well. Sorry, that I couldn't help you, but you are definatelly not alone.
