PSConfig Microsoft.SharePoint.Administration.SPUpdatedConcurrencyException Issue

sharepoint 2013 psconfig an update conflict has occurred

In this article, I would like to walk you through the issue when I am running the PSConfig file in SharePoint 2013.

Issue “PSConfig Microsoft.SharePoint.Administration. SPUpdatedConcurrencyException”

When I was running PSConfig after installing the patches I got the below error:

SharePoint deveopment training course
sharepoint 2013 psconfig an update conflict has occurred
sharepoint 2013 psconfig an update conflict has occurred

Root Cause

This error will occur when you try to update sites, tables, and databases because of the race condition ( more than one threads access shared data and try to change it concurrently). However, this is a rare occurrence while you do the SharePoint upgrade.


To fix this concurrency issue, execute the below command in SharePoint 2013 PowerShell window.

$strCmd=”start “+””””” /affinity 1 “+”””C:\Program Files\Common Files\microsoft shared\Web Server Extensions\15\BIN\Psconfig.exe””” + ” -cmd” +  ” upgrade” + ” -inplace” + ” b2b” + ” -wait”
cmd.exe /c $strCmd

What exactly this command will do?

This command will ensure that it will execute the psconfig using single core affinity! Follow the below steps to verify the same:

1. Open the Task Manager
2. See details
3. Locate the running process for Psconfig
4. Right-click the process and select Set Affinity: you should see only CPU 0 selected
5. Let the Psconfig process complete

Once this command is executed successfully, it will show the success message as below.

Hope this helps, happy administration in SharePoint!!!.
