[Pdns-users] Signal 9 crash...

[Marc van de Geijn]

At this moment I'm working on a little script to automaticly switch to
another recursor server when the current one stops working (I don't have
control over de recursor server I'm using and the one in PDNS 2.9.10 is not
stable).

After changing the IP address in the pdns.conf file, the script sends a
signal 9 to the pdns server. This signal causes the PDNS server to crash
after the Respawn with the following messages in the logfile.

Can somebody help me solve this problem or tell me what I'm doing wrong?

Kind regards,
Marc
