Gitlab ci-sidekiq process running but down in gitlab-ctl status

Hi,

I’ve recently upgraded gitlab from version 8.11.11 to 11.4.5. It’s working well and I don’t have any issue. The reason for the question is when i check the status of gitlab, I see that the ci-sidkiq process is showing as down, but I don;t see any issues in Gitlab and the CI runner I have still works as it should.

# ./gitlab-ctl status
run: alertmanager: (pid 1856) 691402s; run: log: (pid 1121) 691409s

And this is it running:

Does anyone have any recommendations?
