Currently we have issued when upgrade CUCM to 11.5 SU11. Sometimes the GUI process Install freezes, we try to refresh and the process is running again, but when the install process running for 3 hours and freezes again, suddenly when we refresh the install process cancels itself. The ISO unmounted from CD and we check CPU from RTMT is 99%. But the latest version has appeared in inactive version. I attached log install
Please Advice for me
