VMs Crashing

Hey guys, for two days in a row now my VMs have crashed.  I am not sure what is causing this but I have to stop and restart the array to get them to run again.  I will post the relevant log info here and attach the diagnostics from right when it happened.  Please note that for some reason, the VM logs show 18:34 for the time when everything else is showing 13:34.
