Do you have very long slugs ?
There is a maximum post length but it is usually pretty large and defined by php.
If that is the case you would have issues saving very long page content.

When nav saves it sdds this to the page
[code]
$('div.bodycontent').before('<div class="<?php echo $success ? 'updated' : 'error'; ?>" style="display:block;">'+<?php echo json_encode($msg); ?>+'</div>');
$(".updated, .error").fadeOut(500).fadeIn(500);
[/code

Maybe look at the response code when you submit in dev tools and see what its outputing.
