I tried it and it actually only happens on 9x. I found that postgres
tries to shmat to an address which I have no idea about where it comes
from. The problem with that address is, that it's neither a multiple
of SHMLBA, nor does postgres call shmat with the SHM_RND flag. For some
reason the address is ok on NT.
So, Jason, do you have an idea why that happens? Two questions come to mind:
- How does postgres evaluate that address and why does it only fail on 9x?
- Why does postgres use a fixed address at all, instead of using NULL to
let the system decide which address to use?
