Why is that?? It simply means that the system has pushed out some dirty pages during a time that the system required lots of memory. Whatever caused that demand has gone away now, but the pages are still stored in swap so that they may possibly be used again (the in-core copies reclaimed without having to re-page them out...assuming they aren't modified again). -DG David Greenman Core-team/Principal Architect, The FreeBSD Project
