Unfortunately, not yet.

If your operational environment allows, can you try to run the server
with the following setting?
- a smaller max-cache-size value (e.g., 128MB), and
- a relatively smaller datasize value (e.g., 512MB)
Then memory allocation will start failing at some point, and some
unusual log messages will possibly appear, which might help diagnose
the problem.
BTW:
- does this also happen if you build named without threads?
- does this also happen for BIND 9.4?
According to the information so far, this problem seems to happen only
for 9.5 built with threads.
Thanks,
