[Bug 1549788] Re: bind9 9.10.3.dfsg.P2-4 crash on exit

[Doug Smythies]

Same for me:

Feb 29 14:45:51 DOUG-64 named[1202]: connection refused resolving '19.82.133.155.in-addr.arpa/PTR/IN': 37.59.161.64#53

Feb 29 15:35:02 DOUG-64 systemd[1]: bind9.service: Failed with result 'core-dump'.

As of the last few days, I also have an apparmor issue:

Feb 29 15:35:33 DOUG-64 kernel: [25130.612529] audit: type=1400
audit(1456788933.480:15): apparmor="DENIED" operation="open"
profile="/usr/sbin/named" name="/proc/sys/net/ipv4/ip_local_port_range"
pid=4932 comm="named" requested_mask="r" denied_mask="r" fsuid=109
ouid=0

but if I set that apparmor profile to "complain" mode, then my kernel
will crash during the shutdown phase of a re-boot.

Otherwise, and as far as I know the DNS is actually working properly.
