I have just updated two plugins: embed and include.
It would seem that the bug does not occur any more since.
Principle of most share of pages is to include the other documents by coding for example {{page > stats:butbut_comportement}}
The inclusive documents being regularly reconstructed by pages external PHP in the wiki.
Your experience would be precious to me to validate the principle of these pages.
