The ELF alignment requirement for 32bit executables is 64k. Since there was no MAP_ALIGN flag for mmap, the default alignment returned from mmap was made to be the same as the ABI-required executable requirement. Have you tried passing a 8K alignment requirement to mmap? I believe it defaults to 64k.... I'm not sure will do what you want, but there's a good chance. - Bart -- Bart Smaalders Solaris Kernel Performance [EMAIL PROTECTED] http://blogs.sun.com/barts _______________________________________________ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
