Servers Check version 15 - agent issue

Environment:
ServersCheck is installed on Windows Server 2016 Standard , x64
Processor: : 1 Intel Xeon 2.2 GHz
Memory: 16 GB
ServersCheck Agent: Windows Servers (Windows Server 2016 Standard , x64) are installed as virtual machines
hosted on VMWare host
Processor: : 1 Intel Xeon 2.2 GHz
Memory: 16 GB
Tests Performed on one of our servers:
We did a report using perfmon (CPU, Memory ) for a period of 24 hours before and after installation of agent: no
change

1. In relation to Windows agent: cpu, memory, diskspace:
a. Error reading data from Windows Agent
Timeout, no reply from server
b. Server1: The windows agent is unstable. He goes down many times ( > 10 times per day) without reason on the
monitored server: the server is correct, no errors in event viewer, cpu usage small, memory usage small.
c. Server2: The agent is very greedy in cpu: the cpu tops out at 100% although these servers, before the installation
of the agent ServersCheck, are very quiet: CPU does not exceed 10%, So it is the agent who has introduces this
CPU load.
vs. This behavior was not present with the old version 12 version
d. The version I use is the most recent on the serverscheck site. Likewise for the serverscheck agent for windows.

Sherif there is no change in the agents between v12 and v15. Alternate solution was provided in different topic couple of days ago.
