New datapoint: it looks to me like most the vm_map_entry's in the kernel map are not "wired," and the map itself is marked pageable. That is, most of the entries wired counts are 0, and the kernel map flag VM_MAP_PAGEABLE is set. The unwired entries include entries covering the kernel text and data. Is it possible that the kernel is trying to swap kernel pages? (Swap is off!) Dave -- David Young OJC Technologies dyoung%ojctech.com@localhost Urbana, IL * (217) 278-3933 ext 24
