If this is reproducible, then drive and/or media are at the edge of
failure.

Did you already try with preventing automatic formatting of the BD-R by
  -use-the-force-luke=spare=none
?

To my (personal, subjective, questionable) experience the write quality
is better without Defect Management (e.g. with growisofs on unformatted
BD-R). I conclude this from the fact that i could write and read BD-RE
and BD-R without Defect Management which nearly always failed if it was
enabled.

I am thrifty and thus normally use BD-RE for experiments. But i already
had occasions where BD-R were unreliable.
In the end, either the poorly compatible media were used up or the
drive dropped dead completely. I had to replace 1 Pioneer and 1 LG during
the last 8 years of BD burning.


Have a nice day :)
