GeoEvent server and problem with CPU

[deleted-user-GKyg-xriCvci]

Hello, we are using ArcGis Enterprise and additional Server together with GeoEvent are installed on separate machine (Windows Server 2016, processor Intel Xeon E5-2673 v4 @ 2.30GHz). Last week, we upgraded all the Enterprise components from 10.5.1 to 10.6. After couple of days, machine started using almost 100% CPU all the time. In task manager it shows that application responsible for usage is Java (TM) Platform SE binary. When I stop the whole GeoEvent Server, CPU starts working fine. So I suspect the problem is somewhere behind GeoEvent. I tried to analyse log files but I do not really know what should I search for. Did anyone experience similar problem? I will appreciate any help.

We have the exact same problem. However our configuration is slightly different:

Windows 2012, 4 CPU, 16 GB RAM - HyperV virtualisation.

ArcGIS Server 10.5.1 and GeoEvent 10.5.1 

The same problem  occurs - Java (in the ArcGIS Server folder) consumes all the CPU (99-100%) rendering the machine unresponsive. One the machine is restarted it will work again.

I think it might be related to the NMEA events that we receive as I started seeing these errors in the GeoEvent Server log files:

An unexpected error has occurred while translating a NMEA message. Error: Failed to create new GeoEvent: GeoEvent Definition for GUID(39ec2c55-5d51-43ee-a8ce-5f7d8904abd8) does not exist..

My suspicion is that GeoEvent does not really like to be upgraded and needs to be completely removed before installing a new version. Just a hunch tho.
