Communication between OneClick and the SpectroSERVER(s).
CA Spectrum - 10.X Operating System - Linux / Windows
Have all users log out of the OneClick console and restart tomcat on the OneClick system. Restart Tomcat Services, restarting tomcat on the OneClick system forces OneClick to make a fresh connection with the SpectroSERVER(s).
If this does not resolve the issue or the issue should reoccur after restarting tomcat on the OneClick system to open a case with CA Spectrum Support.
