It is fixed in FreeBSD by completely re-writing the VM system from scratch. Along with this a whole hoard of bugs were fixed when the VM buffer cache and free memory pool became integrated as well. I/O performance of FreeBSD systems really scream now. :) Now, there may be other bugs in FreeBSD that have been fixed in BSD/OS, but a swap leak is *NOT* one of them. :) Nate -- nate@sneezy.sri.com | Research Engineer, SRI Intl. - Montana Operations nate@trout.sri.MT.net | Loving life in God's country, the great state of work #: (406) 449-7662 | Montana. home #: (406) 443-7063 | A fly pole and a 4x4 Chevy truck = Heaven on Earth
