This message can also occur if the page, in this case
[[See this creative writing]], does not exist. The text
should be updated to also mention this case.

This is now usually caused by replication lag, which is why I updated the
message a week or so ago to suggest trying again in a minute or two if it is a
recently changed page. Lag is typically a second or two, rises to many minutes
while searchindex update or special pages update are running. The slaves can't
usally update searchindex fast enough and for the special pages they have to run
the query to update the special page themselves. For the spacial pages, using a
MyISAM table, updating with the option not to replicate and then using load
table from master on the slaves for all wikis is one alternative approach.
Faster special reports is the real solution, though.

This may be occurring very frequently.

Currently, this bug has made ''two'' versions of [[Talk:Main Page]]
inaccessible. It is thus impossible to revert the vandalism that has occurred.
This really must be fixed.

I guess that should be ''three''. Isn't there any way to edit comments here?

This kind of problem happens if DBs (master and slave) are out of sync.
This is monitored and most often fixed within a few minutes. 1.4 will
contain code to automatically detect delays and fall back to the master.

Same error message just occurred for
http://meta.wikimedia.org/w/index.php?title=Template%3AFil_de_l%27information&diff=88375&oldid=86162
Later article version was from two weeks ago.
Repeating the request worked ok.
meta has been running 1.4beta4 for about one day.

The previous error occurred shortly after editing.
Updating an article causes the previous revision to be added to the "old" table
(with a generated "old_id" number), which is also subject to database
replication lag.

I'm guessing that, since there aren't frequent reports of users screaming about
missing page text, this was fixed with the transition to the 1.4 branch, eons ago.
