Thread:Project:Support desk/mediawiki hangs/reply (2)

I think I've identified the problem. I was trying to import a page I had exported from wikimedia.org: African_American_boy_selling_The_Washington_Daily_News.png

Somehow this tied mysql (actually mariadb) in knots. Restarting the database server seems to have ended the hangs. I don't know what all that page needs that's weird. But retrying the import generated all sorts of errors:
