Automatic merge sometimes fails to merge after successful build
It has happened to me twice now (on Gitlab.com, 8.3.2) that a merge marked for automatic merging did not actually merge automatically after the build successfully completes (no merge conflicts).
In the most recent case, the last build finished over 10 minutes after the MR was marked for automatic merging, so there wasn't a race condition with that. I don't have a way of reproducing the behavior. In order to get the MR to merge, I need to cancel the auto merge and reissue the merge command in Gitlab.
