SharePoint 2013 psconfig an update conflict has occurred

Issue “PSConfig Microsoft.SharePoint.Administration. SPUpdatedConcurrencyException”
When I was running PSConfig after installing the patches I got the below error:

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

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

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

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