While importing Template:Edit protected to beta enwiki, I received the following error:

Import failed: A database error has occurred. Did you forget to run maintenance/update.php after upgrading? See: https://www.mediawiki.org/wiki/Manual:Upgrading#Run_the_update_script Query: INSERT IGNORE INTO globalimagelinks (gil_wiki,gil_page,gil_page_namespace_id,gil_page_namespace,gil_page_title,gil_to) VALUES ('enwiki','15850','10','Template','Edit_protected','Padlock-dash.svg'),('enwiki','15850','10','Template','Edit_protected','Template-info.png') Function: GlobalUsage::insertLinks Error: 1205 Lock wait timeout exceeded; try restarting transaction (10.4.0.53)

If it's helpful, I noticed that immediately before this occurred, all pages were taking 20-30 seconds to load (and still were after).

Severity: normal
