Time for me to correct something I said in my last response. Our current implementation of SYSVSHM does actually store it's data in a named anonymous memory region/object and it does this by using the internal version of "mmap". ...but his has nothing to do with supporting large files and doesn't in itself having anything to do with why SYSVSHM memory objects consume kernel VM. Anyway, I suppose I shouldn't have bothered responding to any of this. Sigh. -DG David Greenman Core Team/Principal Architect, The FreeBSD Project
