It seems like application is "flooding" ndbd with
WRITE KEY='0x0 0x63' VALUES SET = 0, 2, 3

And that some other values (i.e col 1 or col > 3) is not null

And..that API is sending multiple WRITE on same key within same execute *1
Note that *1 yeilds deliberatly undefined behaviour
  (but crash should ofcourse not happen)
