[Pdns-users] Attempt to print an unset dnsname

[Klaus Darilion]

Hi!


My PowerDNS 4.0.4 (with some modifications) exits often with
"Exiting because communicator thread died with STL error: Attempt to
print an unset dnsname"

I have some hard time to find where this happens. The logged stack trace is:

Do you have any ideas how to debug this issue?

Thanks
