There have been multiple reports since yesterday that even after lint errors on pages have been fixed, the Special:LintErrors page isn't getting updated.

There are 3 potential culprits in the pipe (Parsoid, Linter extension, Changeprop / Job Queue)
(a) Regression in Parsoid no longer linting pages (b) Something broken in changeprop / job queue that linter update jobs aren't getting run (c) (b) Some breakage in the Linter extension wrt updating the database
Looking at the [[https://www.mediawiki.org/wiki/Topic:U8oc5a9rj7me4qt0|trwiki report]], the user is reporting that linthint is continuing to work properly. Since linthint makes a request to the API to find lint errors on a page which initiates a fresh Parsoid parse of the page, we can rule out a regression in Parsoid.
So, that leaves us with either a problem in changeprop or in the linter extension itself.
