My PowerDNS 4.0.4 (with some modifications) exits often with

I have some hard time to find where this happens. The logged stack
trace is:
Sep 26 14:53:19 cc-reg-vie1 pdns[16802]:
/usr/sbin/pdns_server-instance(+0x192b33) [0x7f75e06c8b33]

You can pipe this log through ‘c++filt’ to get more readable
function/method names. To really debug it, rebuild pdns with
CFLAGS=‘-O0 -ggdb’ CXXFLAGS=‘-O0 -ggdb’, then run it under gdb,
with a breakpoint on “ throw std::out_of_range("Attempt to print an
unset dnsname”);”, which in my copy of pdns lives in dnsname.cc on
line 165.
Kind regards,
