Smirk. Let's redirect this to chat. I mean to say by that, if the problem was recognized on a given system it would happen on that system if memory overcommit *wasn't* the policy. The difference is that far less programs would be able to run. Nearly all programs that use lots of malloc, do it sparsely. Stopping memory overcommit would cause a system to begin returning correct data to malloc, at the cost of a small fraction of the number of processes being able to successfully run. One way of looking at this is to focus directly (and only) on malloc, but that is looking at things with blinders on, and asking for fixes that would cause egregious harm to nearly all users. > ----------------------------+----------------------------------------------- Chuck Robey | Interests include any kind of voice or data chuckr@picnic.mat.net | communications topic, C programming, and Unix. 213 Lakeside Drive Apt T-1 | Greenbelt, MD 20770 | I run picnic (FreeBSD-current) (301) 220-2114 | and jaunt (Solaris7). ----------------------------+----------------------------------------------- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
