--- type: reference --- # GitLab application limits GitLab, like most large applications, enforces limits within certain features to maintain a minimum quality of performance. Allowing some features to be limitless could affect security, performance, data, or could even exhaust the allocated resources for the application. ## Number of comments per issue, merge request or commit > [Introduced](https://gitlab.com/gitlab-org/gitlab/issues/22388) in GitLab 12.4. There's a limit to the number of comments that can be submitted on an issue, merge request, or commit. When the limit is reached, system notes can still be added so that the history of events is not lost, but user-submitted comments will fail. - **Max limit:** 5.000 comments ## Number of pipelines per Git push > [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/issues/51401) in GitLab 11.10. The number of pipelines that can be created in a single push is 4. This is to prevent the accidental creation of pipelines when `git push --all` or `git push --mirror` is used. Read more in the [CI documentation](../ci/yaml/README.md#processing-git-pushes). ## Retention of activity history > [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/issues/21164) in GitLab 8.12. Activity history for projects and individuals' profiles was limited to one year until [GitLab 11.4](https://gitlab.com/gitlab-org/gitlab-foss/issues/52246) when it was extended to two years, and in [GitLab 12.4](https://gitlab.com/gitlab-org/gitlab/issues/33840) to three years. ## Number of webhooks On GitLab.com, the [maximum number of webhooks](../user/gitlab_com/index.md#maximum-number-of-webhooks) per project, and per group, is limited. To set this limit on a self-managed installation, run the following in the [GitLab Rails console](https://docs.gitlab.com/omnibus/maintenance/#starting-a-rails-console-session): ```ruby # If limits don't exist for the default plan, you can create one with: # Plan.default.create_limits! # For project webhooks Plan.default.limits.update!(project_hooks: 100) # For group webhooks Plan.default.limits.update!(group_hooks: 100) ``` NOTE: **Note:** Set the limit to `0` to disable it. ## CI/CD limits ### Number of jobs in active pipelines > [Introduced](https://gitlab.com/gitlab-org/gitlab/issues/32823) in GitLab 12.6. The total number of jobs in active pipelines can be limited per project. This limit is checked each time a new pipeline is created. An active pipeline is any pipeline in one of the following states: - `created` - `pending` - `running` If a new pipeline would cause the total number of jobs to exceed the limit, the pipeline will fail with a `job_activity_limit_exceeded` error. - On GitLab.com different [limits are defined per plan](../user/gitlab_com/index.md#gitlab-cicd) and they affect all projects under that plan. - On [GitLab Starter](https://about.gitlab.com/pricing/#self-managed) tier or higher self-hosted installations, this limit is defined for the `default` plan that affects all projects. This limit is disabled by default. To set this limit on a self-hosted installation, run the following in the [GitLab Rails console](https://docs.gitlab.com/omnibus/maintenance/#starting-a-rails-console-session): ```ruby # If limits don't exist for the default plan, you can create one with: # Plan.default.create_limits! Plan.default.limits.update!(ci_active_jobs: 500) ``` NOTE: **Note:** Set the limit to `0` to disable it. ## Environment data on Deploy Boards [Deploy Boards](../user/project/deploy_boards.md) load information from Kubernetes about Pods and Deployments. However, data over 10 MB for a certain environment read from Kubernetes won't be shown. ## Merge Request reports Reports that go over the 20 MB limit won't be loaded. Affected reports: - [Merge Request security reports](../user/project/merge_requests/index.md#security-reports-ultimate) - [CI/CD parameter `artifacts:expose_as`](../ci/yaml/README.md#artifactsexpose_as) - [JUnit test reports](../ci/junit_test_reports.md) ## Advanced Global Search limits ### Maximum field length > [Introduced](https://gitlab.com/gitlab-org/gitlab/issues/201826) in GitLab 12.8. You can set a limit on the content of text fields indexed for Global Search. Setting a maximum helps to reduce the load of the indexing processes. If any text field exceeds this limit then the text will be truncated to this number of characters and the rest will not be indexed and hence will not be searchable. - On GitLab.com this is limited to 20000 characters - For self-hosted installations it is unlimited by default This limit can be configured for self hosted installations when [enabling Elasticsearch](../integration/elasticsearch.md#enabling-elasticsearch). NOTE: **Note:** Set the limit to `0` to disable it. ## Wiki limits - [Length restrictions for file and directory names](../user/project/wiki/index.md#length-restrictions-for-file-and-directory-names).
