I've noticed these warnings when browsing DiscussionTools-related error logs: "Multiple writes to a write-once: limitreportdata discussiontools-limitreport-timeusage". They greatly increased in rate on 2022-11-10: https://logstash.wikimedia.org/goto/8c490d9343a900fa4df1f68f160fd300
The warning is logged here from Parsoid code: https://codesearch.wmcloud.org/search/?q=Multiple+writes+to+a+write-once
The value is written here from DiscussionTools code: https://codesearch.wmcloud.org/search/?q=discussiontools-limitreport-timeusage&files=%5C.php%24 (just once, as far as I can tell…)
Can anyone explain what this really means, and how do we fix it?
