Pages missing from ‘manage pages’

Hello all

I have several hundred pages in my wordpress site. Not all of my pages are appearing in the admin ‘manage pages’ section. I’m using wordpress 2.0.

The pages seem to stop listing after about number 346/347 fairly consistently. Could this be a server time out problem or similar? I don’t get any error messages or anything useful like that, the pages merely stop listing.

Any help much appreciated.

Cheers
Matt
