(I also mentioned in https://bugs.isc.org/Ticket/Display.html?id=37059)

I receive the following on maybe every query on macmini.lab with 
--with-tuning=large:

socket.c:2790: setsockopt(20, SO_RCVBUF, 16777216) failed: No buffer 
space available

macmini:system jreed$ grep setsockopt.*No.buffer systests.output | wc -l
12738

(I had seen this for weeks but didn't report it yet.)

Also see ISC-Support #6886 for FreeBSD.

I think the --with-tuning shouldn't result in this noise by default.
If this is okay behavior, some suggestions about it should be included 
in the README and/or FAQ.
