Well, there's your problem.

FreeNAS 9.2.1.x requires 4GB of RAM for UFS.
FreeNAS 9.2.1.x and 9.3 require 8GB of RAM for ZFS.

Ok I have a similar issue. Same as above.

I installed 9.3 onto a SSD just fine. Then I find out that you can't use NFS in 9.3 to mount to VMWare (seriously?). So I try to downgrade to 9.2.9 and I get the above error consistently. I have done the install several times with the same result.

Server has dual 6 core CPU's and 48Gb of RAM. 24 300Gb 15K drives.

I am stymied here.

NFS works fine with VMware and the reason it didn't work is probably related to the reason you boot doesn't work. I chalk it up to user error. If you provide more information on what exactly you are doing we might be able to figure it out.

you can't use NFS in 9.3 to mount to VMWare (seriously?)

ESXi NFS works fine under 9.3 - seriously. Performance will be poor without an SLOG device but that's expected behavior.
