x/build: some Gerrit CLs are getting into a state where they can't be updated #40147
x/build issues (builders, bots, dashboards)
Someone must examine and confirm this is a valid issue and not a duplicate of an existing one.
gopherbotlogs, there are a number of CLs where a reviewer fails to be added due to the error "Change nnn may not exceed 5000 updates. It may still be abandoned or submitted. To continue working on this change, recreate it with a new Change-Id, then abandon this one.":
It's not possible to leave review comments on those CLs.
Need to investigate why this is happening.
From initial observations, it might be CLs that GerritBot imported from PRs, where PRs have had large review comments posted (e.g., golang/tools#215 (review)), which might have caused some sort of fail-and-repeat loops to make an excess of 5000 API calls to the Gerrit CL, causing Gerrit to lock those CLs. But I've only looked very briefly so far, more investigation is needed to confirm this or find another explanation.
