BenchVue Causing Instrument Errors and Crashes

Hello,

I just installed BenchVeu 2017 on WIN10 x64. The install worked but now 2 of my 4 Keysight instruments report errors and crash when the PC that runs BenchVue starts up or the web interface is used. Note I have not installed any Apps for BenchVue. The web interface to instruments requires Java, which is no longer on any of the browsers I use.

6.5 digit DMM, 34461A, Firmware 2.14,

“Application AGILIENTLXIWEBSERVICE.EXE encountered a serious error and must be shut down.”

The DMM needs to power cycle to make the error message disappear.

4ch Scope, MSOX3054A, Firmware 2.41

“Checking system integrity”

“System concerns detected:
* The exception 0xC000 0005 occurred at address 0x4027236C. InfiniVision automatically restarted.

The default setup was loaded.
LAN VGA option module fault.”

I have the latest firmware based on the MyKeysight listing of my equipment.

How do I prevent these errors?
What is the best way to safely remove BenchVue and keep my PC stable?
Do I also need to remove the instrument control bundle to prevent these errors?
I would like to control these instruments with Python 3.x and would appreciate a pointer to related reference material.

Previously before the WIN7 to WIN10 upgrade an older version of BenchVue ran on this hardware. This software was removed before the WIN10 update.

Thanks for your help with this.

We've been looking into this, but have not been able to reproduce it. The scope software may have detected a problem with the LAN module, so make sure it is installed properly. But the fact that you are getting the same error on two devices would tend to indicate something else. The mDNS service (AGILENTLXIWEBSERVICE) might be the culprit, so you might try stopping and restarting it. Or uninstall/reinstall the Keysight LXI Server. By the way, Java is not required except for remote programming SCPI applet and firmware upgrades.

Hi Brian,

Thanks for replying. The Ethernet and display on my MSOX work. The only PC service related to Keysight was “Keysight mDNS Responder” Service. I did not see any Agilent mDNS service or AGILENTLXIWEBSERVICE.

I decided to slowly purge all Keysight programs starting with BenchVue. It took until I purged the “Keysight IO Library Suite 2017” before I could boot my PC connected to Keysight instruments without crashing them.

This is a security hole for Aglient/Keysight instruments. A network interaction should not crash them. I have attached the Keysight programs that remain on my system from the BenchVue 2017 and Keysight_Instrument_Control_Bundle_3.2017. This may help Keysight improve their software. Do you recommend removing the remaining programs from the BenchVue install?

I need more help related to the 34461A. When it is accessed using a web browser (Firefox or Edge) the same crash message

“Application AGILIENTLXIWEBSERVICE.EXE encountered a serious error and must be shut down.”

occurs. I need to reboot the DMM to make the message go away. The DMM seems to work when the message is present. The firmware: A.02.14-02.40-02.14-00.49-01-01, which I believe is the latest.

When I click on the browser key (one below the home key) the enter password screen pops up for a second then disappears then I get the message “Java not detected”.

The same web browsers interact with the MSOX without causing a crash.

How do I prevent the DMM from crashing?

I would still like to interact with my Keysight instruments using Python. Please point me to any helpful materials on this.

Thanks.

Hi @seen - your observation about the problem going away when you uninstalled the Keysight IO Libraries Suite makes sense, as its the PC side of the mDNS software stack.

Have you tried disabling mDNS on your instruments? To do that:

On the DMM:

Choose Utility --> I/O Config --> LAN Settings --> LAN Services --> More 1 of 2 --> mDNS Off --> Done --> Apply Changes
Reboot the instrument and the PC to verify the workaround

On the Scope:

Choose Utility --> I/O --> LAN Settings --> Config --> Uncheck Multicast DNS --> Apply.
Reboot the instrument and the PC to verify the workaround

Thanks for your input on mDNS. Please note that the network configuration use to work. The scope web interface works with IO Libraries and BenchVue 2017 removed.

I disable mDNS on the DMM, got LAN Status: Fault. Then manually configured the IP address, mask, gateway, and DNS addresses. LAN status: good. Reboot PC and DMM.

Using the web interface results in the same error:

“Application AGILIENTLXIWEBSERVICE.EXE encountered a serious error and must be shut down.”

The network configuration is,

Pinging the DMM works and does not cause an error.

When I click on the instrument key (one below the home key) the enter password screen pops up for a second then disappears then I get the message “Java not detected”. Repeating this I get,

Parse error in script

ASP scripting compilation error: '80131509'

Description:

In file: /PasswordFront.asp
On line: 47

I have found yet another problem while using the DMM. The Keysight 34461A DMM duplicates the screen images of the first USB screen save. The latest screen image is not sent to USB.

The TCP stream during the web interface startup is,

So my Keysight 34461A DMM problems are:

Web access causes,

“Application AGILIENTLXIWEBSERVICE.EXE encountered a serious error and must be shut down.”

The web interface to DMM data and control does not work.
USB screen save duplicates the first saved image.
BenchVue 2017, crashes DMM and Scope.

Is there something else that I can do that will restore normal operation?

Thanks.

Can you send me the Wireshark log? We can analyze that and see if we can't reproduce the crash here at Keysight. Send me the Wireshark log to connectivity.support@keysight.com

Hi Hognala,

Did you receive my WireShark file (sent May 8)? Do you have any more input to solve my issues?

I also found another concern with Keysight software. After installing the BenchVue packages and then removing some of them, I noticed that when every time I selected an Excel workbook the PC made a sound notification, which was annoying. Disabling, with Excel, the Keysight.CommandExpert.Addons.Excel prevent this annoying sound.

My current Keysight software issues are:

BenchVue 2017 issues

Crashes 34461A DMM and MSOX 3xxx Scope.
The Keysight.CommandExpert.Addons.Excel causes an annoying windows sound every time any workbook is selected. Disabling the addon prevents this issue.

My next steps will attempt to remove more remnants of the BenchVue install. The uninstaller left folders etc. on my system. Input on cleanly removing all BenchVue software and files would be appreciated.

A pointer to using Python with Keysight instruments would also be appreciated.

Thanks for your help with this.
