Re: ZFS kmem_map too small.

So, I just had another of these panics:

panic: kmem_alloc(131072): kmem_map too small: 400011264 total allocated

what I did to provoke it:
zfs rollback room/freebsd_at_presnap

 From loader.conf:
vm.kmem_size=536870912
vm.kmem_size_max=536870912
vfs.zfs.arc_max=409715200
vfs.zfs.prefetch_disable="1"
