软件崩溃多次

我们刚刚从Vee 8.5升级到9.3，Windows XP升级到Windows 7.过去两周左右，我们在软件中运行了一些先前的测试。
没有出现任何问题。
不，我们正在进行下一次测试，在过去3天内，软件已经崩溃了4次或更多次。
现在得到：错误号：751异常类型：System.Runtime.InteropServices.COMException Agilent34980A：IO错误：VI ERROR_NCIC：不是控制器负责。错误代码：0x80044212调用.NET对象时出错错误调用是
在事务编号1中，事务正在调用Reading = agilent34980AClass.Measurement.Read（ChannelList）对象标题：读取传感器对象类型：IVI-COM在UserFunction中：readSensor ----------------- To
我这似乎表明安捷伦34980A走出了远程模式。
问题是当这个错误弹出时，没有人在34980A的前面板附近...有关如何调试此问题的任何想法？
谢谢，格雷格

  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
