Overview

 

In SolarWinds Platform 2025.2, you may observe warning messages in the JobEngine logs indicating errors distributing throttling data to remote agents. These errors resemble the following:
 
2025-11-24 03:47:17,733 [369] WARN SolarWinds.JobEngine.Routing.Router - (null) Error distributing throttling data to router 'sw-agent://5772b9a3-6c4d-46c3-97b1-d31b18acaed2/'. SolarWinds.JobEngine.UnableToReachAgentException: Unable to connect to the remote agent with id '5772b9a3-6c4d-46c3-97b1-d31b18acaed2'
 
Similar warnings appear repeatedly for different agent IDs, indicating communication failures between the JobEngine service and remote agents. These errors contribute to increased memory consumption by the SWJobEngineSvc2 process on Additional Polling Engines.
