First occurrence on 2022-12-16, only seen on mediawikiwiki.
I only noticed the issue because I was reviewing the logs for a different problem with the same error message (T321317).
I happened to notice this issue today because it generated ~18M log messages over the course of 20 minutes.
Looks like pretty much all requests to /w/rest.php/www.mediawiki.org/v3/page/pagebundle/Help%3AMagic_words/5943756 ... But, the question is: why are there those many requests to that url? In any case, this is likely an edge case error that we could plug soon.
First estimation: it's not "those many requests to that URL, it's "oops, we have an infinite loop situation going on here". So first, fixing that, and then understanding why it happens in the first place.
This comes from
<translate>The parameter <tvar name=\"1\"><code>nowiki</code</tvar>> usually removes the link around the filepath (which can't be seen in this example).</translate>
(note the interleaving of code and tvar tags.)
Still need to harden against that sort of things, but it's indeed quite edge-casey.
