Have there been any configuration changes or recipes added to the 
site recently?  I suspect that either the PHP configuration or the
PmWiki configuration has been modified and this is causing the
links to stop working.

If the pages are actually _changing_ -- i.e., the links
are actually losing data in the source text, then I suspect
a recipe is modifying the data somehow (possibly something using
a replace-on-save pattern).

I doubt it has anything to do with url length -- if length was a
problem, I'd expect characters to be chopped from the end of the
link.  Since it's targeting a specific field in the url (i.e.,
rID=... ), I suspect a recipe is modifying the text somehow.
