Pages allocated more than 15 seconds ago would be released by the VM since that's how long it takes to release them isn't it? :-) But don't assume I know exactly what I'm talking about here... :-) To be honest, I did jump to a conclusion that Andrei's observation is due to streaming data from disk at video rates (which 10MB/15sec is), since I've often encountered that problem, and I'm working on similar hardware to Andrei (not quite the same) which is primarily an MMUless platform for video playback. -- Jamie _______________________________________________ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev
