Thread:Project:Support desk/No login page after 1.21.3 to 1.22 upgrade - Uncommitted DB writes?/reply (6)

[Tue Dec 17 15:44:17 2013] [error] [client 10.10.241.232] Script timed out before returning headers: index.php, referer: http://testdomain/wiki/index.php?title=Special:UserLogin&returnto=Main+Page

Followed of course by the not-having-a-dedicated-500-page error, but there was a lot more debugging enabled for the run that I listed above, so I was assuming that would be more useful.
