expected log entries on sendto ENOBUFS errors

[nusenu]

Hi,

I've been pondering with 
"sendto failed: No buffer space available"
errors using unbound [0].

To see how BIND behaves on the same box
I switched from unbound (and pdns-recursor) to BIND
and don't get any similar log warnings.

Now my question is:

What log entries (if any) would BIND produce
on ENOBUFS sendto [1] errors? (at what severity)

OS: FreeBSD 12
BIND 9.13.5

thanks!
