That's a known bug with quite a few boards. Nobody has tracked it down
yet. You're probably the first person to notice these zeros.
Can you sprinkle POST codes liberally all over the map and note down
when the zero sending starts? Since the delay is so long, observing POST
codes on a POST card should work fine.
By the way, such a bug is much less likely to ever happen in v3.
