Using CU4D for Troubleshooting at ControlUp

A user discussed using CU4D for troubleshooting an issue where a user’s laptop and Citrix session froze and required a forced reboot. There was high memory usage on Edge and WebView2. Others suggested using CU4D to see process stops and app hangs, power events, and on-demand PowerShell scripts. Someone also suggested looking into network latency features and historical graphing for wireless signal strength or network usage. Event ID 1002 for Citrix Workspace could also help identify the issue.

Hi,

How do you guys use CU4D when troubleshooting an issue?

Today we had a user who said her laptop and Citrix session just froze, so she had to force a reboot.

When checking CU4D, I could see high memory usage, and that Edge and WebView2 were the two processes consuming the most memory. The Windows Event Log didn’t show anything, as we haven’t added any additional logs yet.

Have you added a lot of entries under Event Log Collection, or do you run PowerShell scripts to retrieve events?

This time I used “Collect diagnostics” in Intune but I was hoping CU4D would make this easier.

Hey! For scenarios like this, CU4D gives you a few layers without needing to fall back on Intune Diagnostics:

• Process Stops & App Hangs: you can see if Edge/WebView2 actually crashed or hung (with exit codes) right around the time of the freeze

• Power Events: the force reboot should show as an Unclean Restart (Kernel-Power 41), no need to dig through Event Viewer manually

• On-demand PowerShell scripts: run directly from the device details panel, results come back immediately. Way faster than waiting for an Intune diagnostics package to download

I would recommend reaching out to your account team for training or assistance setting up your environment for a specific use case.

@member I’ve seen this in my own environment a few times and more often than not, a full session freeze was related to a graphics driver issue – assuming nothing was going on with their network connection.

Do you leverage the network latency features and historical graphing for wireless signal strength or network usage? Those have helped me out a ton in the past.

For Citrix Workspace directly, try looking for Event ID 1002 under Application logs

Here are a couple I’ve noticed in the last few days:

Description:

The program wfica32.exe version x.x.x.x stopped interacting with Windows and was closed.

C:\Program Files (x86)\Citrix\ICA Client\wfica32.exe

The program SelfService.exe version x.x.x.x stopped interacting with Windows and was closed.

C:\Program Files (x86)\Citrix\ICA Client\SelfServicePlugin\SelfService.exe
