Issue reported here: https://forum.pfsense.org/index.php?topic=78356.msg472781#msg472781 Most unbound doc places mention setting it at up to 8m. I'm sure it would be possible to investigate more and find a way to make unbound+FreeBSD be able to go higher than 8m. But probably 8m is sufficient for everyone anyway (judging by what the unbound docs seem to assume will be a good value on a busy system). Anyway, here is my easy fix for this. Someone else feel free to investigate more if they really need to set so-rcvbuf higher.
Limit unbound so-rcvbuf: 8m
