I suspect you have compression turned on in ZFS, and there is an unbounded allocation of memory in the ZFS (de)compression code. Kip is working on a patch to put some bounds on it. I've changed my tunables to not allow the ARC to grab ALL of physmem (vfs.zfs.arc_max) and testing a full backup now. Waiting, patiently, for code patch from Kip. -- Larry Rosenman http://www.lerctr.org/~ler Phone: +1 512-248-2683 E-Mail: ler_at_lerctr.org US Mail: 430 Valona Loop, Round Rock, TX 78681-3893Received on Sat May 30 2009 - 23:51:32 UTC
