[Pdns-users] PowerDNS (2.9.22) crash with signal 8 (floating point exception)

[Dmitriy Lyfar]

Hi,

I'm using pdns with my own backend. Previous version I've used was 2.9.21
(from centos repo) and my backend works fine. But we decided to
move to last version (pdns-static, 2.9.22, x86_64) and it can't even run
with my backend. I've got a stack trace from debugging version, which looks
like:

Sep 11 13:28:35 dnsfencetest pdns[15527]: Reading random entropy from
'/dev/urandom'
Sep 11 13:28:35 dnsfencetest pdns[15527]: Got a signal 11, attempting to
print trace:

Sep 11 13:28:36 dnsfencetest pdns[13550]: Our pdns instance (15527) exited
after signal 6

So crash something inside of seedRandom function. I'm confused with this
trace, is there any problems with /dev/urandom? Thank you.
