Please use an ordered list. --> Create an instance, edit `/etc/gitlab/gitlab.rb` `gitlab_rails['gitlab_email_display_name']` to non-ASCII letter. Or update an instance to 16.0.1. (For my case, it's 15.11.3 to 16.0.1) ### Example Project <!-- If possible, please create an example project here on GitLab.com that exhibits the problematic behavior, and link to it here in the bug report. If you are using an older version of GitLab, this will also determine whether the bug is fixed in a more recent version. --> (blank) ### What is the current *bug* behavior? ``` /opt/gitlab/embedded/lib/ruby/gems/3.0.0/gems/activesupport-6.1.7.2/lib/active_support/configuration_file.rb:40:in `include?': incompatible character encodings: US-ASCII and UTF-8 (Encoding::CompatibilityError) from /opt/gitlab/embedded/lib/ruby/gems/3.0.0/gems/activesupport-6.1.7.2/lib/active_support/configuration_file.rb:40:in `block in read' from <internal:kernel>:90:in `tap' from /opt/gitlab/embedded/lib/ruby/gems/3.0.0/gems/activesupport-6.1.7.2/lib/active_support/configuration_file.rb:39:in `read' from /opt/gitlab/embedded/lib/ruby/gems/3.0.0/gems/activesupport-6.1.7.2/lib/active_support/configuration_file.rb:14:in `initialize' from /opt/gitlab/embedded/lib/ruby/gems/3.0.0/gems/activesupport-6.1.7.2/lib/active_support/configuration_file.rb:18:in `new' from /opt/gitlab/embedded/lib/ruby/gems/3.0.0/gems/activesupport-6.1.7.2/lib/active_support/configuration_file.rb:18:in `parse' from /opt/gitlab/embedded/service/gitlab-rails/lib/gitlab_settings/settings.rb:17:in `reload!' from /opt/gitlab/embedded/service/gitlab-rails/lib/gitlab_settings/settings.rb:27:in `method_missing' from /opt/gitlab/embedded/service/gitlab-rails/sidekiq_cluster/cli.rb:202:in `sidekiq_exporter_enabled?' from /opt/gitlab/embedded/service/gitlab-rails/sidekiq_cluster/cli.rb:210:in `metrics_server_enabled?' from /opt/gitlab/embedded/service/gitlab-rails/sidekiq_cluster/cli.rb:188:in `start_metrics_server' from /opt/gitlab/embedded/service/gitlab-rails/sidekiq_cluster/cli.rb:162:in `start_and_supervise_workers' from /opt/gitlab/embedded/service/gitlab-rails/sidekiq_cluster/cli.rb:136:in `run' from /opt/gitlab/embedded/service/gitlab-rails/bin/sidekiq-cluster:11:in `<main>' ``` ### What is the expected *correct* behavior? <!-- Describe what you should see instead. --> Gitlab running with low CPU usage. <!-- ### Relevant logs and/or screenshots Paste any relevant logs - please use code blocks (```) to format console output, logs, and code as it's tough to read otherwise. --> <!-- ### Output of checks If you are reporting a bug on GitLab.com, uncomment below --> <!-- This bug happens on GitLab.com --> <!-- /label ~"reproduced on GitLab.com" --> <!-- #### Results of GitLab environment info Input any relevant GitLab environment information if needed. <details> <summary>Expand for output related to GitLab environment info</summary> <pre> (For installations with omnibus-gitlab package run and paste the output of: `sudo gitlab-rake gitlab:env:info`) (For installations from source run and paste the output of: `sudo -u git -H bundle exec rake gitlab:env:info RAILS_ENV=production`) </pre> </details> --> <!-- #### Results of GitLab application Check Input any relevant GitLab application check information if needed. <details> <summary>Expand for output related to the GitLab application check</summary> <pre> (For installations with omnibus-gitlab package run and paste the output of: `sudo gitlab-rake gitlab:check SANITIZE=true`) (For installations from source run and paste the output of: `sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production SANITIZE=true`) (we will only investigate if the tests are passing) </pre> </details> --> ### Possible fixes <!-- If you can, link to the line of code that might be responsible for the problem. -->
