[emergency] gitlab ci running on endless loop
Hi, gitlab team,
I get a serious issue, now my gitlab ci is runing on endless loop.
because i set a tag push on file ".gitlab-ci.yml", and the gitlab ci will run default on tags, and when I know this ,i changed ".gitlab-ci.yml" and add [except: tags]. of course I operated on the same repo, so after this I checked the pipeline, i found so many new pipelines running on the old commitid that i dont set [except: tags], but when i stop the pipelines manually, and test the ci pipeline again on this repo, same things happen again, i dont know how to solve this issue, and i dont know why happen again and again, which operation was triggered the old commitid run ci pipelines on the endless loop
now my gitlab latency is very high, i can not check the version, the gitlab-runner is 10.2.0
datetime:20171225, still appeared, i already stop the gitlab-runner, how long the queue, how to check?
already deleted the tag three days ago, but now appeared again?

GitLab 9.5.0 GitLab Shell 5.8.0 GitLab Workhorse v3.0.0 GitLab API v4 Git 2.13.5 Ruby 2.3.3p222 Rails 4.2.8 postgresq 9.6.3
