If you want a daemon to be fully in core, call mlockall(). Here's one way to do that without changing the daemon's source: http://superuser.com/questions/196725/how-to-mlock-all-pages-of-a-process-tree-from-console (I've always only done this with my own code explicitly calling mlock) If you don't explicitly lock things into memory, file I/O can and will cause idle pages to get pushed out. It happens less often if you manipulate swappines. -- greg _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
