TROUBLESHOOTING
GitLab Troubleshooting and Self-Managed Infrastructure Recovery Services
GitLab troubleshooting is a service that identifies and resolves component-based issues such as web access problems, 502/500 errors, repository lockups, application server interruptions, CI/CD pipeline errors, Container Registry delays, disk fullness, and failed upgrade (upgrade) processes.
What is GitLab Troubleshooting and Self-Managed Infrastructure Recovery Services?
GitLab hosts a complex architecture with many microservices. Therefore, to diagnose an issue, merely reviewing the main logs is insufficient to reach the root cause.
The process involves analyzing the statuses of various services including Puma (application server), Sidekiq (background job queue), Gitaly (Git storage service), PostgreSQL (database), Redis (cache/queue), Nginx (web server), GitLab Runner, and Container Registry. All technical interventions are carried out in a secure manner, ensuring the integrity of the database and Git repositories.
Service scope
Component-Based Deep Analysis
Puma, Sidekiq, Gitaly, PostgreSQL, Redis, and Nginx logs, service statuses (gitlab-ctl status), queues, and disk I/O values are reviewed.
Secure Intervention and Correction
Data security and storage integrity are prioritized to address misconfigurations, stuck queues, faulty service contexts, or insufficient resource allocations.
Functional Acceptance and Validation
User access, repository access (Git clone/push), CI/CD pipeline processing, and Registry service functionalities are verified to be functioning properly.
WHO IS IT FOR?
Who is it for?
- Enterprises that cannot access the GitLab interface or experience 502 Bad Gateway or performance issues.
- Development teams whose CI/CD pipeline processes are stuck, facing runner connection errors, or Container Registry issues.
- Organizations with self-managed (customized/server-based) GitLab architectures that need services restored after a failed upgrade.
- Teams unable to access Git projects due to disk fullness, Gitaly lockups, or PostgreSQL/Redis queue backlogs.

Frequently asked questions
Why does a '502 Bad Gateway' error occur in GitLab?
A 502 error typically results from the failure to start the Puma service, communication issues with the Gitaly layer, insufficient RAM/CPU resource pressure, misconfigured Nginx/Reverse Proxy settings, or database inconsistencies after an upgrade.
How can it be determined whether a CI/CD pipeline error originates from the GitLab server or the Runner service?
Job logs, Runner service statuses, executor configurations (Docker, Shell, Kubernetes), and network access permissions are examined. The issue is differentiated between the GitLab API layer, Runner environment, or the code/script stage within the project.
Should a version upgrade (upgrade) be performed when an active GitLab issue occurs to resolve the problem?
If the root cause is not a known crisis/bug in the current version, performing an upgrade during an active incident is not recommended. Attempting to resolve the issue before a system upgrade increases the risk of data loss and service interruption.
