We have started to get intermittent "Invalid OTS Token" errors today when creating a new user profile.  Most of our attempts to create a user profile work fine and, prior to today, we recieved an occaisional error every couple of weeks.  We have found that if a customer gets this error (nine so far today) and they refresh the checkout page to initiate a new transaction, their next attempt works fine.

Is anyone else seeing an uptick in these errors today?  Any good way to mitigate?
