Process count spikes every 2 minutes

Hi!

In our self-hosted GitLab CE instance (docker-based), we see a spike in the processes from about 230 to about 450 every 2 minutes.

Since there is a bunch of GitLab cron jobs that run every two minutes: Who can help me identity, which one it is?

The following is an excerpt of the TOP command with the additional processes:
