Additional poller services for Syslog, Traps, and Module Engine are flapping

Updated March 11th, 2016

Overview

The additional poller services for Syslog, Traps, and Module Engine are flapping on the server. The additional poller also show as down in the Web Console. To validate this, check the Business layer logs and information service logs and you will see errors with remote host rejecting the connection or certificate error. 

Environment

  • All NPM versions

Cause 

The certificate thumbprint does not match with the primary Solarwinds Server. 

Resolution

  1. Check the certificates using MMC on both servers. 
  2. If they are mismatched, repair the core
