You may experience timeouts or HTTP 502 errors and is recommended to increase this
value by updating the `puma['somaxconn']` variable in your `gitlab.rb`.
## `exec request failed on channel 0` or `shell request failed on channel 0` errors
When pulling or pushing by using Git over SSH, you might see the following errors:
- `exec request failed on channel 0`
- `shell request failed on channel 0`
These errors can happen if the number of processes from the `git` user is above the limit.
To try and resolve this issue:
1. Increase the `nproc` setting for the `git` user in the `/etc/security/limits.conf` file on the nodes where `gitlab-shell` is running.
Typically, `gitlab-shell` runs on GitLab Rails nodes.
1. Retry the pull or push Git command.
