McAfee Agent (macmnsvc) uses port 8081 for wake-up communication with ePo. QoreStor uses the same port for the policy manager.
原因
When McAfee Agent is installed in the QoreStor Server Linux OS it can affect the QoreStor Services and the system will enter in Maintenance Mode (Manual Intervention). This is because both services are trying to use the port 8081.
解决办法
As this port is hard coded in QoreStor the only alternatives are:
Uninstall McAfee Agent from the QoreStor server
Use a different port for McAfee Agent communication to ePo.
