works for me, could be overloaded database response though.

I just got the same error on the same page. If it's an overload response, can
the detection and reporting be improved? Or is it really a database server
having to be shutdown urgently?

The reported IP address was 10.0.0.3, "Served by friedrich.wikimedia.org ...".

from within function "indexShowToplevel". MySQL returned error "1053: Server
shutdown in progress (10.0.0.24)".

Yes, that's an overload issue. The long queries get killed and the error isn't handled well.

This was from http://en.wikibooks.org/wiki/Special:Allpages but a few minutes
previously it was returning the more common "(SQL query hidden)" variant without
the backtrace. See bug 1109#c11 for another "gone away" error with a backtrace
from "action=submit" on sl.wikipedia.org.
