Hi, We use FreeBSD 11.2-STABLE for 5 recursive name servers, with PowerDNS recursor as the actual name server software.
I recently complained on the pdns-users list that some graphs based on information from the name server process stopped working after a while (typically a week or less): https://mailman.powerdns.com/pipermail/pdns-users/2019-January/025739.html Bert Hubert of PowerDNS led me to https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=227689 and it definitely looks like this is the bug causing the disappearing graphs that I see. In https://mailman.powerdns.com/pipermail/pdns-users/2019-January/025742.html you can see the effect on the getrusage() call - in short, the values simply stop incrementing after a while. I fixed the problem by following the link from https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=227689 to https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=76972 which has an attachment (kern_resource.c.patch.txt) at https://bz-attachments.freebsd.org/attachment.cgi?id=50537 After adding this patch and rebooting, the problem has not recoccurred in nearly two weeks. I'm reasonably sure that the problem really has been fixed. I checked the code at the same place in HEAD, from https://svnweb.freebsd.org/base/head/sys/kern/kern_resource.c?view=markup and the bug appears to still be present in HEAD. So, I'd love it if somebody could - Update bugs 76972 and 227689 to note that this affects more than one person. - Fix this in HEAD and hopefully also MFC to 11.2-STABLE.
