I have a program in which a number of executables use an mmap'ed file
to share memory. This used to work fine, but we updated to Redhat ver
5.2, and now the changes made by one process are no longer seen by the
others.

I am using the MAP_FIXED flag--the mmap'ed memory contains absolute
pointers.

The program has two possible interfaces, an X interface and a console
interface. Everything appears to work okay when using the X interface.
It's under the console interface that the problem appears.

Any ideas? Is mmap() different?

Sincerely
