Overview

This article provides brief information and steps to resolve the error when the Core Businesslayer plugin crashes on Start up. The following error message is seen:

 

2016-02-15 13:12:16,761 [8] ERROR SolarWinds.BusinessLayerHost.PluginInstanceAppDomain - Plugin "Core Business Layer" failed to start.
System.IO.IOException: The file exists.

The error above is referencing InternalGetTempFileName during the certificate update.

Environment

NPM 11.5

Cause 

The issue is caused by the large number of files in C:\Windows\Temp.

Resolution

  1. Stop the Orion Services using the Orion Service Manager.
  2. Clean out the Windows temp directory.
  3. Restart the Orion Services using the Orion Service Manager. It should no longer crash the Core Plugin on Start up.

 

If the Web Console still will not open, you can check the following logs to confirm the CoreBusinessLayer is now starting correctly:

  • C:\ProgramData\Solarwinds\Logs\Orion\BusinessLayerHost
  • C:\ProgramData\Solarwinds\Logs\Orion\Core.BusinessLayer

 

If they are starting correctly run through removing and rebuilding the website. Refer to https://support.solarwinds.com/Succe..._Orion_Website.
