Environment

The SpectroSERVER is on a host that shares resources.

Cause

The problem is due to shared resources when running CA Spectrum on virtual hosts.  If there isn't enough free memory for the online backup to occur, then the online backup fails and the SpectroSERVER will not start back up.

Resolution

Make sure there is enough free memory available to the SpectroSERVER.  CA Spectrum requires dedicated resources per SpectroSERVER when running the SpectroSERVER on virtual hosts.
