> Aside from the Powerdns upgrade and a bunch of upgrades for other packages, apt-get also installed an upgrade for Libbotan (from 1.10.8-2 to 1.10.8-2+deb8u1) and after some testing the combination of the Powerdns and Libbotan packages turned out to be the source of the problem: when I downgraded both packages back to 3.4.1-4+deb8u4 and 1.10.8-2 respectively, everything was fine again.

I'd appreciate it if the security team / uploaders of the new
botan1.10 and pdns 3.4.1-4+deb8u5 packages could chime in on this.

Many thanks,
