[Pdns-users] pdns 3.4.7 crashes or behaves strange

Tue Nov 17 18:49:29 UTC 2015

Hi!

I have update our pdns from 3.3.3 to 3.4.7. As always I built the
packages myself (using the debian-pdns folder in the tarball) on Ubuntu
10.04. I updated the DB schema, but when I start pdns it crashes
multiple times as shown below. After respawing several times, pdns
starts up and answers queries. But after receiving a NOTIFY it somehow
locks up and does not respond to DNS anymore.

I also attached my config.

Any ideas what could be the problem, or how I debug it myself?

Thanks
Klaus
