Thanks for filing this bug in Ubuntu.

I filed this bug upstream for now:

If this happens again, please let us know, as having a way to reproduce it reliably would be very helpful.

This bug was fixed in the package bind9 - 1:9.11.5+dfsg-1ubuntu1

bind9 (1:9.11.5+dfsg-1ubuntu1) disco; urgency=medium

  * Merge with Debian unstable. Remaining changes:
    - Build without lmdb support as that package is in Universe
    - Don't build dnstap as it depends on universe packages:
      + d/control: drop build-depends on libfstrm-dev, libprotobuf-c-dev and
        protobuf-c-compiler (universe packages)
      + d/dnsutils.install: don't install dnstap
      + d/libdns1104.symbols: don't include dnstap symbols
      + d/rules: don't build dnstap nor install dnstap.proto
  * Dropped:
    - SECURITY UPDATE: denial of service crash when deny-answer-aliases
      option is used
      + debian/patches/CVE-2018-5740-1.patch: explicit DNAME query could
        trigger a crash if deny-answer-aliases was set
      + debian/patches/CVE-2018-5740-2.patch: add tests
      + debian/patches/CVE-2018-5740-3.patch: caclulate nlabels and set
        chainingp correctly, add test
      + CVE-2018-5740

    - d/extras/apparmor.d/usr.sbin.named: add missing comma at the end of the

    - Add a patch to fix named-pkcs11 crashing on startup. (LP #1769440)
      [Fixed in 1:9.11.4.P1+dfsg-1]
    - Cherrypick from debian: Add new dst__openssleddsa_init optional symbol
      (it depends on OpenSSL version) (Closes: #897643)
      [Fixed in 1:9.11.4.P1+dfsg-1]
  * Added:
    - d/p/enable-udp-in-host-command.diff: fix parsing of the -U command line
      option (LP: #1804648)
    - d/p/fix-shutdown-race.diff: dig/host/nslookup could crash when interrupted
      close to a query timeout (LP: #1797926)
    - d/t/simpletest: drop the test as it requires
      network egress access that is not available in the Ubuntu autopkgtest
