Overview

Orion services regularly crash and the following error is found in the application event log:

Application: SolarWinds.DataProcessor.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.OutOfMemoryException
Stack:
   at System.Runtime.Fx+AsyncThunk.UnhandledExceptionFrame(System.IAsyncResult)
   at System.Net.LazyAsyncResult.Complete(IntPtr)
   at System.Net.LazyAsyncResult.ProtectedInvokeCallback(System.Object, IntPtr)

   at System.Threading._IOCompletionCallback.PerformIOCompletionCallback(UInt32, UInt32, System.Threading.NativeOverlapped*)

Environment

All Orion Platform versions

Cause 

A memory fragmentation occurs in the services due to a large dataset.

Resolution

Perform the following steps to enable faster memory cleaning:

  1. Back up the Config file for the affected service and make sure the backup is placed outside of the Orion directory.  
  2. Navigate to the Config file for the affected service, for example, the SolarWindsInformationServiceV3 config file is found in: C:\Program Files (x86)\Common Files\Solarwinds\Information Service\V3 and the file name is SolarWinds.InformationService.ServiceV3.exe.config
  3. Edit the Config file and add the <gcServer enabled="true"/> line in the runtime section:
    <runtime>
    <enforceFIPSPolicy enabled="false"/
    <gcServer enabled="true"/>
    </runtime>
  4. Save the file and restart the services.
