Re: Ubuntu service file is missing Restart parameter
Hi Ondrej, sorry, I really thought it's clear enough, but as I just found, the problem presents in releases for Ubuntu 20.04, 18.04 and maybe older also. It's all about the content of /lib/systemd/system/named.service Release for Ubuntu Jammy 22.04 LTS (1:9.18.1-1ubuntu1.3) contains "Restart=on-failure" parameter. Releases for Ubuntu Focal 20.04 LTS (1:9.16.1-0ubuntu2.12) Ubuntu Bionic 18.04 LTS (1:9.11.3+dfsg-1ubuntu1.18) and maybe older also are missing "Restart" parameter. I found this problem with friend, when Bind9 on Ubuntu 20.04 exited with SIGV signal and keeps down (systemd did not restart the service).

Ubuntu service file is missing Restart parameter
Hi there, I just discovered that default Bind9 systemd service file for Ubuntu is missing "Restart" parameter. Is there any reason? Service file for Debian contains "Restart=on-failure" Thanks Blažej -- Visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list ISC funds the development of this software with paid support subscriptions.

Resolver failures after stale-answer enabled
Hello, few days ago I updated our recursive resolvers at AS50242 from Debian 10 to 11 to be able to enable stale-answer afer Facebook incident. However, today I got bug reports from customers. Their browser often fail at page loading with DNS_PROBE_FINISHED_NXDOMAIN. After few seconds (and after browser DNS re-query) page will load correctly. In Bind9 log I see many of messages like: Oct 27 11:34:13 srv-snv-production named[576109]: configuration.ls.apple.com resolver failure, stale answer unavailable Oct 27 11:34:13 srv-snv-production named[576109]: client @0x7fc71806cd58 10.202.42.196#58876 (configuration.ls.apple.com): view clients: query failed (SERVFAIL) for configuration.ls.apple.com/IN/TYPE65 at query.c:5832 Oct 27 11:34:13 srv-snv-production named[576109]: configuration.ls.apple.com resolver failure, stale answer unavailable Oct 27 11:34:13 srv-snv-production named[576109]: client @0x7fc7180715a8 10.202.42.196#49219 (configuration.ls.apple.com): view clients: query failed (SERVFAIL) for configuration.ls.apple.com/IN/A at query.c:5832 After I turned off stale-answer, problem looks to be resolved. I'm attaching huge debug log of above failures - hope somebody will find problem from this.
