The first thing I would try to do is upgrade and 9.0 isn't supported anymore regardless of the ZFS issue. Migrating to STABLE is probably your best chance of success, but 9.1 probably would work too. You also didn't indicate amd64/i386 or any other system specs. IIRC, vm.kmem_size had to set higher even on AMD64 for that era. -- Adam Vande More
