It may be caused by caching, by the way.

It is due to caching, at least on Wikimedia web sites, where this is enabled.
The query page caching utilities will cache up to a maximum of 1000 results to
save time (these things are cached due to the performance cost, after all) -
1000 results is considered sufficient for people to work on before the next
re-cache, in most cases.

Not really a bug.

Is this maximum of 1000 changeable in LocalSettings.php (just not listed at http://
www.mediawiki.org/wiki/Manual:Configuration_settings#Cache) or is it something to do
with php?

robchur wrote:

The default cache limit is 1000 as defined in
maintenance/updateSpecialPages.php, although individual query pages can override
this in includes/QueryPage.php. At this time, none do.

As of r18162, the limit can be customised via $wgQueryCacheLimit.
