ULS Viewer crashes when viewing SharePoint 2013 logs

Hello there,

A quick tip for those who encountered the ULS viewer crash with SharePoint 2013 as my colleagues and me.


  • SharePoint 2013
  • ULS viewer


When opening a SharePoint log containing “verbose” logging with ULS viewer, this one crashes after processing all the data. This makes the tool unusable at some extent.
This issue doesn’t appear if you don’t set the logging level to at least “Verbose“.


Although I don’t know what is going on in the background, the quick fix for this is to disable in the option the feature “correlation tree”.

  1. Open Uls Viewer
  2. Go in menu “Tools/Options…”
  3. Uncheck the option “Enable correlation tree”









Happy troubleshooting !
