That's basically saying something wrote the padding bytes which is unexpected
so either a coding error or something nasty is happening and the data in that
memory location is being overwritten by something else.

You might want to run the zdb via gdb and put a break point at that location.
When it trips output the state of the zio. Might help show what's going on.
