We also started seeing this issue as of 10/17/24. I used gitlab-ctl tail and saw that there were tons of API requests per second happening from my Linux Mint development machine. I suspected it was due to a gitlab issue tracker plugin I had on Neovim, and sure enough quitting Neovim on that machine resolved the issue.
I did a little bit of searching through the GitLab release notes but couldn’t find anything that might have triggered this. I’ve since stopped using the plugin so it’s not a big issue, but I am curious if there are any changes that need to be made to API calls.
