Hi,
We're noticing high CPU usage on one of our location CUCM publisher. What I'm finding is the CPU load is caused by Java ( stvcvad+) user. I did a search for any bugs but didn't find any, can anyone inform why this is happening and how to resolve the issue? Details of my finding are below for review. Any assistance would be greatly appreciated.
