We are new to GitLab we just started with self-hosted GitLab on a docker container on a centos VM. Till yesterday everything was working fine but then Gitlab started responding too slow and sometimes we get error 502. We are not more than 10 users with only 1-2 users connected at a time.
The VM configuration is more than the recommended requirements but I am not able to figure out what the issue is. These are the VM configurations we are using:
- CentOS 7
- RAM 12 GB
- 8 Cores CPU
- 100 GB HDD
Can anyone tell me how to troubleshoot the VM and see what is the issue? I have a very basic knowledge of Linux commands. I read about the unicorn workers that it can increase the response time. Should I change the number from 2 to any other number based on the above settings? Or should leave it as it is?
