I'm currently trying to fix an Orion Additional Polling Engine where the Solarwinds Data Processor service stops with the following error message:
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+IOCompletionThunk.UnhandledExceptionFrame(UInt32, UInt32, System.Threading.NativeOverlapped*)
at System.Threading._IOCompletionCallback.PerformIOCompletionCallback(UInt32, UInt32, System.Threading.NativeOverlapped*)
We've got 3 additional polling Engines and a main poller. The problem affects only one polling engine. The polling engines have the same hardware specifications.
The polling rates on the Polling engines are around 80%. The polling engines have been working at this rate for the past few months but the problem with this poller only started in the last two weeks (no associated config changes).
I've run through the process described here SolarWinds Knowledge Base :: Collector Data Processor and Collector Polling Controller start and stop intermittently but this did not resolve the problem.
Does anyone have any ideas what else to check?
Thanks
