That's a rather serious issue.

First off, are you using anything fancy with text storage (aka External Storage or some of the fancy compression stuff)?

Is there anything in your php error log? If you have logs of your database, is there any errors there, does the record containing the page content get inserted into the text table, etc.

Additionally, the mediawiki debug log (not enabled by default, see How to debug for instructions) may contain relavent information if it is running while an edit is taking place that gets "lost".

(Sorry I can't give any advice that is more specific beyond look at logs. I've never heard of this happening before).
