After recent changes to jenkins setup, the check triggered by gerrit is performed twice. It's been observed on osmo-pcu, libosmocore and osmo-gsm-manuals.
For example: https://gerrit.osmocom.org/#/c/4646/
It's not too bad because the check results are always the same but it still seems like waste of resources.
hmm, weird, I'd have guessed that we still have old gerrit jobs configured that are duplicated by the jenkins-job-builder ones, but it for the link provided, it was the same job building twice for one and the same patch; notably the second was triggered after the first had voted.
Looking at recent builds, they don't seem to be duplicated. Maybe updating the jobs while one is running duplicates triggers, and it was just being an odd false positive instead of a regular failure?
