VI_ERROR_NCIC with 34980A

We had just recently upgrade from Vee 8.5 to 9.3 and Windows XP to Windows 7.  We had run some previous tests in the software over the past 2 weeks or so.  No issues popped up.  No we are running our next test and in the past 3 days the software has crashed 4 times or more.

It now gets:

Error number: 751
Exception type: System.Runtime.InteropServices.COMException
Agilent34980A: IO Error: VI ERROR_NCIC: Not the controller-in-charge.returned error code: 0x80044212

Error occurred while calling a .NET object
Erroring call was in transaction number 1
Transaction was calling Reading = agilent34980AClass.Measurement.Read(ChannelList)

Object title: Read Sensor
Object type: IVI-COM
In UserFunction: readSensor

-----------------
To me this seems to indicate that the agilent 34980A went out of remote mode.  Problem is that nobody was anywhere near the front panel of the 34980A when this error pops up... 

Any ideas of how to debug this issue?

Thanks,
Greg
