FreeBSD 10 iSCSI Target Windows 8.1 Initiator

[dweimer]

I have a FreeBSD 10 server setup, with a 300G iSCSI target backed by a 
zVOL device.  With a windows 8.1 Workstation as the initiator connected 
to it.  I am trying to use it to store VMware Workstation Virtual 
Machines.  However I am having all kinds of crashes of Virtual Machines 
and file corruption with it.  I have found these errors on the Server, I 
setup a Virtual Machine on the workstations local disk, and have had no 
problems.

I am fairly new to using iSCSI on FreeBSD as a target I have ran it as 
initiator connecting to our Lefthand Networks SAN at work, but of course 
that was with the older iSCSI prior to 10.  I am kind of clueless on how 
to go about trouble shooting this issue.  Perhaps I did something stupid 
when I setup the configuration, which is shown below.

auth-group Workstation {
   chap iqn.1991-05.com.microsoft:workstation.dweimer.local *****
}

portal-group WorkstationISCSI {
   discovery-auth-group Workstation
   listen 0.0.0.0
   listen [::]
}

target iqn.2012-06.com.webmail:WorkstationDriveD {
   auth-group Workstation
   portal-group WorkstationISCSI
   lun 0 {
     path /dev/zvol/iscsi/WorkstationDriveD.0
     blocksize 4k
   }
}
