What I noticed is that /status displays the last number of requested URIs just fine with the 32bit version but forgets about some requests (note counter is right) in the 64bit version.
I'm not sure what is getting forgotten.
Is the detailed (extended status) table truncated?
(the thing that looks like this)

If so, is it always truncated at the same entry?
What MPM are you using?
Is it trucated at different points if you change ServerLimit or ThreadLimit?
