Not sure what I did wrong last time, but now I get bus error. I suspect there's some race condition between mmap and rewriting the file that creates the problem. The error seems to happen at offset exactly 0x1000 from the start of the map, which leads me to thinking that maybe the problem is that the page needs to be loaded, but since the file is not there, being overwritten, it can not be loaded anymore. -- Stanislav Malyshev, Software Architect SugarCRM: http://www.sugarcrm.com/ (408)454-6900 ext. 227
