--- Comment #1 from Wout Decr=C3=A9 <wout@canodus.be> ---
Except for the timeouts on the upstream servers, it does not crash the Unbo=
und
server. It is able to recover but it keeps happening every so often.

Workarounds:

# elfctl -e +noaslr /usr/local/sbin/unbound

or

# sysctl kern.elf64.aslr.enable=3D0

or

Disable TLS support for the upstream servers.
