How to detect someone or some problem break the contents of the shm between shutdown and re-start?

I don't understand what you say...

Or, do you misunderstand about the check sum of the each pages?
It is calculated only when writing the pages to disk. not valid when on memory.
The other checksum is needed.


When shutdown is not to check, but to store.
When startup is to check.
