Hi, after 4 months of normal work sudden high CPU usage (48…53%), here are the configuration parameters:  
Windows Server 2016, CPU 2.4 GHz, 16 GB RAM, Ignition 8.04, KEPServerEX6, Database MS SQL Server, on remote PC, approximately 4000 tags running , I took some logs and thread snips:

To be honest, I really do not know where to start from, what the troubleshooting approach should be…any hints?

I wonder why don’t you use newer version of ignition.  
The CPU usage and performance bug is fixed from 8.9.10.
