Thanks in advance. Oh - it was just vm.kmem_size="134217728" and not _many things_. If kmem uses that much RAM there is not much left for applications, but it runs stable for doing the backups. I noticed once that a zpool scrub requires additional kmem to normal use, which might still overflow this box - it is hard on the limit after all. -- B.Walter http://www.bwct.de http://www.fizon.de bernd@bwct.de info@bwct.de support@fizon.de
