PENDING SCCM reboot prompt shown after hiding notification & suppress reboot

[Prakash Modak]

Hello,
I'm using SCCM 19, I've deployed windows update package to servers, check the "Hide in software center notification for all programs" and Suppress reboot for "Servers" and "Workstations".
When the user logs on to the server( RDP), the user is presented with the prompt to reboot the server and gives 15 Min. if users disconnect the RDP session the timer resets and the server does not reboot, but if the user ignores that prompt and stays with the session, server reboots. If no one logs on to server it does not reboot or prompt for reboot.
i'm getting the following message in rebootcoordinator log on one of the server.

I hope I was able to explain my problem.
Can you please help me out, as these servers are in production and are not supposed to reboot before its scheduled time

Thanks in advance
Prakash
