Dell Wyse Device Manager Version 5.0 WDMServiceLog process pegs processor at 100%

Problem

Dell Wyse Device Manager Version 5.0 is installed onto a Windows Server 2012 R2 server:

… and you notice that the WDMServiceLog (32 bit) / RptSvcLog.exe process consistently consumes close to 100% of the CPU process pegging the processor at 100% and allowing the server down to a crawl:

Solution

While the following may not be the best solution for the issue as it’s more of a workaround, it was the only one I could find while searching:

http://www.technicalhelp.de/forums/topic/problem-with-wdm-service-log-makes-cpu-usage-go-to-100/

The suggestion was to disable the WDM Service Logs logging service found here in the Preferences options:

Disabling this service will cause the WDMServiceLog (32 bit) / RptSvcLog.exe never to run and therefore fixes the issue.

Attempting to register a package from a script file (.RSP) on a Wyse Device Manager manager fails with: “Unable to connect to the HTTP Repository”

Problem

You need to move Package Manager Images from one WDM server to another by following the instructions found at this URL:

… but notice that you are unable to register the image because it fails with:

Unable to connect to the HTTP Repository

Proceeding to use the Test Connection feature for the Software Repository as such:

… fails with the error:

Name: HTTP Connection
Progress: Test Testing Complete
Status: Failed

Clicking on the Errors tab displays the following error:

[Error:Not Available] [WebDAV error:Failed to upload buffer. HTTP Response Code: 401Remote File Path: {A33AADB7-443F-4113-A478-D5A07E5518E0}.tmp Error Code: 401]

Solution

While there could be various reasons why this error would be thrown, one of the users is if the rapport service account password has expired and requires a new password to be set.  To determine this, launch the Computer Management console on the Wyse Device Manager server and navigate to the Local Users and Groups –> Users node, then open the rapport service account properties:

Notice that the User must change password at next login is checked which means the password has expired and must be changed.  Proceed by unchecking the checkbox and check the Password never expires checkbox:

Run Test Connection again for the Software Repository to ensure that the test completes successfully:

You should now be able to register the image.

Solution

As the Wyse Z90QQ7P was the new model that was just released, I was unable to find a solution through searching the internet so I ended up reaching out to Wyse technical support and was told that we had to install a WDM 5.0 MR pack to resolve the issue.  At the time of writing this, 2 maintenance releases was available:

1. WDM5.0_MR1_WRK_HF050026414
2. WDM5.0_MR1.1_WRK_HF050027314

I tested installing MR1 first then MR1.1 and can confirm that both of them resolves this issue.
