If I remember correctly, AIX sends a signal to all processes asking them to free up memory. (Processes ignore this signal by default.) If nobody responds, then it selects a victim and blows it away. I think it is nice to processes that catch the signal and try to free up memory in that it won't kill them first. (What would you call such a signal, SIGDIET?) I guess memory overcommit is desirable in a "worse is better" kind of way, because it is clearly not "the right thing." :-( (see section 2.1 of http://naggum.no/worse-is-better.html) -matt [cc:'s trimmed] To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-hackers" in the body of the message
