Description

Making a request for http://localhost/api.php?action=visualeditor&format=json&paction=parse&page=Main_Page&uselang=en results in long pauses until Parsoid times out and the request fails.

git bisecting mediawiki core brings me to https://gerrit.wikimedia.org/r/#/c/230967/, which was also the cause of T109183. Reverting that helps.

Setting $wgMessageCacheType = CACHE_NONE; obviously also resolves the issue.

It's getting late so I'm giving on debugging. Let me know if you need any more info to go on.

@Arlolra, there is quite a lot of contention for Aaron's time -- if you'd like Aaron to look at this, please (1) ask, and (2) provide more details.

Ha, funny guy!

Yes, sorry, assigning @aaron was quite rude.

I'll dig a little deeper.
