jayvdb added a comment. Due to https://gerrit.wikimedia.org/r/226057, the pywikibot test framework wont be tracking this problem on wikidata. It will still see the problem if it occurs on other wikis. I expect that it could happen on any of the (many) other Wikimedia wikis which have a policy <https://meta.wikimedia.org/wiki/Non-free_content> of only using files hosted on Wikimedia Commons. e.g. Czech WP Special:ListFiles <https://cs.wikipedia.org/wiki/Speci%C3%A1ln%C3%AD:Seznam_soubor%C5%AF> lists only one file.
As the failing query uses `rcnamespace=6|7`, it might be an unusual edge case. However if the same query with only `rcnamespace=6` also fails badly, regularly, and the FORCE INDEX suggests it might, then this bug is also affecting more typical usage of the API. However, the problem may also be unique to https://phabricator.wikimedia.org/tag/wikidata/, as it has a very large RC feed which is likely to be an aggravating factor in the performance of the query. Can the ops team identify how frequently this exception is happening? Has it started occurring more frequently in the last week? On very active wikis with very few files?
