How to solve the 3621 error in Gitlab

Gitlab is a widely used open source code hosting platform, but during use, you sometimes encounter some errors and problems. Among them, Gitlab 3621 error is a relatively common problem. This article will introduce in detail the specific solutions to the Gitlab3621 error.

1. Causes of Gitlab 3621 error

Gitlab 3621 error is usually caused by too many concurrent accesses. When the number of visits on the Gitlab server is too large, the server will experience a response delay or resource exhaustion, resulting in the Gitlab 3621 error.

2. Solution to Gitlab 3621 error

1. Check server resources

First, we need to check the server resources. If the usage of resources such as memory and disk space on the server is too high, the resources need to be released in time. We can use tools such as free, top and other tools to view the resource usage of the server. If you find that resource usage is too high, you can free up resources by cleaning and optimizing the server.

2. Adjust Nginx configuration

If the server's resource usage is normal, then we need to adjust the relevant configuration of Nginx. The specific steps are as follows:

a. Open the Nginx configuration file, usually the path is /etc/nginx/nginx.conf.

b. Find and edit the worker_processes parameter, and modify its value to be the same as the number of server CPU cores, usually 4 or 8.

c. Find and edit the worker_connections parameter, and set its value to the minimum value greater than the current number of concurrencies, usually 8192.

d. Save the configuration file and restart the Nginx service to make it effective.

3. Adjust Gitlab configuration

If the above two methods still cannot solve the Gitlab 3621 error, we need to adjust the Gitlab configuration file. The specific steps are as follows:

a. Open the Gitlab configuration file, usually the path is /etc/gitlab/gitlab.rb.

b. Find and edit the unicorn['worker_processes'] parameter, and modify its value to be the same as the number of server CPU cores, usually 4 or 8.

c. Find and edit the unicorn['worker_connections'] parameter, and set its value to the minimum value greater than the current number of concurrencies, usually 8192.

d. Save the configuration file and restart the Gitlab service to make it effective.

4. Use a high-configuration server

If none of the above methods can solve the Gitlab 3621 error, we need to consider using a high-configuration server to improve server performance and resource usage efficiency, thereby avoiding An error occurred.

In short, although Gitlab 3621 errors are common, as long as we troubleshoot and solve them according to the above methods, we can solve this problem and ensure the normal operation of Gitlab services.
