Hello,

I set up a pretty basic unbound service on FreeBSD 11.2 (based on the
default "local" service) that works fine for me as far as I can see (all
names are resolved etc.).
However, in the unbound logfile I see these messages repeated every minute:

---

Mar 26 11:08:37 unbound[66291:0] notice: failed connection from local

I looked around on the net for quite some time now, but couldn't find
out a reason (nor fix) for this. The remote control interface appears to
work, though, and says everything is ok:

---
# unbound-control -c /var/unbound/unbound.conf status
version: 1.5.10
verbosity: 1
threads: 4
modules: 2 [ validator iterator ]
uptime: 947 seconds
options: reuseport control(ssl)
unbound (pid 66291) is running...
---

Any idea what the error messages might mean? Or are they somewhat bogus (with
all the 0s in there)?
