We have five polling engines running in our environment. Appears Poller 4 and Poller 5 hangs and drop connectivity every few hours since performing a solarwinds repair to fix an website exception error two weeks ago. Not sure what may be causing this issue
We usually restart the polling engine server or disable/enable the NIC to regain polling engine services
No issues with our primary polling engine..
Been working with SolarWinds support but no root cause found.
We are on the following SolarWindsOrion Platform: 2014.1.0, SAM 6.1.0, IPAM 4.1, NCM 7.2.2, NPM 10.7, WPM 2.0.1
Found the following error in "Core.BusinessLayer.log"
