The issue at hand is that a jenkins pipeline job does run and finish normally. But in the UI the job stays until we abort him via the UI. This doesnt appear to often, maybe in 5% of the jobs. It might be a jenkins bug, a problem with reload configuration or just to much traffic on the nodes. I am really not sure. Since all of the "buggy" jobs have a striped progress bar this might be a clue.
What excactly does a striped progress bar mean?
Any other suggestions about the source of this bug is appreciated.
