'ssl handshake failed crypto error' log entries

[Christoph]

Hi,

on our public DoT server running unbound we get a lot (> 20 MB / day)
of the following errors even though we run in verbosity level 0.

Our understanding is that this isn't anything we can do about.
Could you remove these entries from verbosity level 0?
