Cause

Possible root cause is a large ip boundary range in an AutoDiscovery configuration

Environment

Release : Any version of Spectrum running on Linux

Component : Spectrum Core / SpectroSERVER

Resolution

Possible resolutions:

- Decrease the size of the ip boundary range in the AutoDiscovery configurations

- Add the following entry into the $SPECROOT/SS/.vnmrc file and restart the SpectroSERVER process for the change to take affect:
