I used to have vm.kmem_size_max=1073741824 as well but heard it was not 
needed to have both. (it made no change)
I never see my vfs.numvnodes over 60,000 but i have the limit at 400,000 
anyways

All this server does is run nfsd, no apache, no mysql, no rsync, no zfs 
snapshots either.



Jan  1 15:48:09 nfsd kernel: ZFS filesystem version 6
Jan  1 15:48:09 nfsd kernel: ZFS storage pool version 6
Jan  1 15:48:09 nfsd savecore: reboot after panic: kmem_malloc(131072): 
kmem_map too small: 864546816 total allocated

In fact i was going to paste the zpool status here, but typing it in 
caused the server to crash. In short i have 4 drives paired in 2 
mirrors, for a raid 0 + 1 effect, normal SATA drives directly connected 
to zfs.
I have tested this hardware thoroughly without zfs, memory test, make 
buildworld tests, etc so i know it is stable hardware.

I hate to report bad news but i hope this leads to a fix
