Solaris mmap man page states that the system adds two 8K 'red zone' pages to each mapping and then rounds the total mapping to some multiple.
Because of the above, applications that need to mmap power of 2 memory segments will end up wasting large amounts of virtual address space. This design seems to be a bit of an oversight, i.e. mapping red zone pages should be an option when calling mmap, because not all applications need it. Is there a way to force mmap not to map red zone pages? A system tunable? _______________________________________________ opensolaris-code mailing list opensolaris-code@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/opensolaris-code
