Sometimes several times in a day I see the wired amount shown in top rise to over 6GB (of 8GB) bringing the system to a crawl. When wired gets over 7GB the system rarely recovers. I am now running 10.2-STABLE r292646 on corei7 with 8GB and ZFS FS This is my everyday desktop running xfce and a variety of gui apps. I use a small script to allocate several GB of ram that gives the pressure needed to start releasing some wired, provided I can get in early enough. Not sure how to gather any helpful info for this. -- FreeBSD - the place to B...Software Developing Shane Ambler
