I imagine pdns-recursor doesn't quit fast enough, and the init script may not do enough checking. > ii sysvinit-core2.88dsf-59.9 amd64 > System-V-like init utilities If you need a fix for this in stable, I'd suggest switching over to systemd, which handles this situation just fine.

Bug#892610: Address already in use /etc/init.d/pdns-recursor restart
Package: pdns-recursor Version: 4.0.4-1+deb9u3+b1 When restarting pdns-recursor with the initscript, "/etc/init.d/pdns-recursor restart", we sometimes get an Address already in use Exception: Mar 11 06:55:09 recurse01 pdns_recursor[30857]: Exception: Resolver binding to server socket on port 53 for 0.0.0.0: Address already in use This is problematic whenever this is done automatically and it never comes up again. Effectivly resulting in no pdns-recursor running. This does not happen always, for example when trying to reproduce it right now, it restarts correctly. It seems to happen while being in heavy use or running for a while longer. Whenever we run "/etc/init.d/pdns-recursor stop", wait a few seconds and "/etc/init.d/pdns-recursor start" again it always works. So it seems like a timing issue, being sometimes too fast starting pdns-recursor again before the socket is completely closed. $ cat /etc/debian_version 9.4 $ uname -a Linux recurse01 4.9.0-6-amd64 #1 SMP Debian 4.9.82-1+deb9u2 (2018-02-21) x86_64 GNU/Linux $ dpkg -l |grep sysvinit ii sysvinit-core2.88dsf-59.9 amd64 System-V-like init utilities ii sysvinit-utils 2.88dsf-59.9 amd64 System-V-like utilities $ dpkg -l |grep systemd ii libpam-systemd:amd64 232-25+deb9u2 amd64 system and service manager - PAM module ii libsystemd0:amd64232-25+deb9u2 amd64 systemd utility library ii python-systemd 233-1 amd64 Python 2 bindings for systemd ii systemd 232-25+deb9u2 amd64 system and service manager ii systemd-shim 10-3 amd64 shim for systemd
