Device does not have a Network Element Driver registered error displayed though NSO installation was successful with devices: Device does not have a Network Element Driver registered error displayed though NSO installation was successful with devices
 As per Link Ly triage analysis, this issue seems to be related to python3 crashing on NSO VM which is due to the memory leak known issue. This was impacting the NED packages to go into operation down state and NED registration issue for all devices.Note: The NSO VM (ubuntu 18) has sufficient resources (16 CPU, 64 Memory, 350 GB HD.) allocated but still memory crash issue is seen even with 2 services. This is interrupting testing ON/OFF.Workaround: Restarting ncs service with force package reload helped to resolve the issue. NED packages were updated to open UP state and devices were in-sync.
