Hi!
I was doing a ports rsync from a zfs to /usr/ports (ufs). That worked
fine. The crash happend as I started to copy (parallel to the rsync) a
huge file from a nfs server to the zfs.
For 512 MB RAM I've set:
kern.maxvnodes="25000"
vfs.zfs.prefetch_disable="1"
vfs.zfs.arc_max="52428800"
vm.kmem_size_max="402653184"
vfs.zfs.zil_disable="1"
[root@filer ~]# zpool status

scrub: none requested
