I doubt it's Windows bug, more likely just lucky timing. I checked provided process dump - it is deadlocked in a code related to applying templates and sending events. There were execution errors for template auto apply scripts - in that case server generates event - and this event generation from within auto apply code somehow caused deadlock. I will investigate it further. As a workaround I suggest to check auto-apply scripts for possible errors.
