[Pdns-users] Segmentation fault

[Massimo Bandinelli]

Hello,

I'm trying to replace bind with powerdns (2.9.20), because it's really
faster in load and reload.

I'm trying using the bind (2) backend and just over 300,000 zones.
I find that pdns will return a "segmentation fault" randomly on me
generally during a bind-reload-now command.  Any help in
diagnosing and resolving this problem would be greatly appreciated. I
need to remove bind. A cold-boot of bind needs 7 hours :( with pdns only
30 minutes.

My operating system is Slackware 10.2
My powerdns version is 2.9.20 dynamic linked and I tried the static one
too with the same results.
