Random Config Download Error: NcmBussinessLayerPlugin.log

The following error appears in the Web Console while manually downloading configurations:

Error Processing results. See NcmBusinessLayerPlugin log for details


Then further in NcmBusinessLayerPlugin.log:

ERROR SolarWinds.Cirrus.BusinessLayer.DAL.ComparisonCacheDAL - Unable to cache diff results due to exception: System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown


NCM version 7.4



The error is occurs when there is not enough memory for the Business Layer to process the  request. 


1. Open the Orion Install directory. The default location is C:\Program Files (x86)\SolarWinds\Orion.

2. Open SolarWinds.BusinessLayerHost.exe.config.

3.  Find the following line:

<add key="ForcePluginsInSeparateProcess" value="False"/>

4. Replace it with: 

<add key="ForcePluginsInSeparateProcess" value="True"/>

5. Save the file. 

6. Restart Orion Services for the changes to take effect.


This allows to run the different Business Layer modules in their own separate processes, thus increasing the total memory available to the module service.
