I ran this test multiple times on a recent devstack (Antelope) and could
not reproduce it. Since it's 5 years old I'll close since there have
been a number of changes in the DB code since then. Please re-open if
you see it again.

Title:
  bulk creation of security group rules fails StaleDataError

Status in neutron:
  Invalid

Bug description:
  Concurrently creating (many) security group rules in a security group,
  either posting concurrently directly to the api, or by using heat
  fails (on queens) with:

  Retry wrapper got retriable exception: UPDATE statement on table 'standardattributes' expected to update 1 row(s); 0 were matched. wrapped /usr/lib/python2.7/site-packages/neutron/db/api.py:126

  StaleDataError: UPDATE statement on table 'standardattributes' expected to update 1 row(s); 0 were matched.

  I've written a small script to reproduce this.

  https://gist.github.com/jsm222/2b7db15eaebe69111793359c9a585823

  Example usages:
  python secruletest.py concurrent --auth-url http://127.0.0.1:5000/v3 --username demo --project-name demo --domain-id default --rules-amount 200
  or
  python secruletest.py heat --rules-amount 200 --file-out /tmp/heat.yaml

  The heat template is just written not applied, the first example makes
  a security group named NeutronSecurityGroupRuleTest (can be set with
  --security-group-name ) and begins posting rules concurrently.

  It is reproducible on rdo packstack queens, and also fails on
  production environment (Ubuntu based queens)
