Versions of MediaWiki prior to 1.4 use[d] an arbitrary constant
(MAX_INCLUDE_REPEAT, with the default value 5, at the top of
includes/Parser.php) to limit the number of times the same template
could appear on a page. This was primarily a kludge to avoid the
possibility of someone including a template in itself and thus causing
infinite recursion. Version 1.4 includes proper protection against
such an attack, and therefore has no such arbitrary limit.

A somewhat rambling bug report which tracked this issue is at

Workaround: increase the constant; true solution: upgrade to version
1.4 (still officially in beta, but happily running all Wikimedia sites
for many weeks now).
