Impact

  • [NixOS] ElasticSearch instances will be restarted.
  • [Gentoo] PostgreSQL 9.3 instances will be restarted.

NixOS platform

  • Fix cluster detection for elasticsearch2 and elasticsearch5 roles (#100251).
  • Provide Python 3.5 and 3.6 for manual installation via nix-env (#100534, #100644, #100759).

  • ElasticSearch startup: improve behaviour when /srv/elasticsearch contains old files (#100722).
  • Fix occasional build error in firewall configuration (#100755).
  • Adjust our swap check: instead of relying on relative usage and “almost empy”, we now consider more than 1G of usage to be “too much” (#100605).
  • Tune HAProxy timeout settings for Graylog (#100770).
  • Don’t reboot VMs due to high load (#100612).

Gentoo platform
