      I have installed agent2 on 25 Windows Servers and installed the plugins. 
      4 out of 25 Windows Servers have their Zabbix Agent2 service crash intermittently with no information shown in the logs.
      All hosts are running on Windows Server 2022
      The agents only crash when they are reporting to both servers, when they only report to one server there are no issues. 
      Both passive and active checks are in use.
      Agent2 version 7.4.3 
      Server Version 7.4.0 and 7.2.0

      On the zabbix server side, the logs show that the server could not contact the agent and temporarily disables the Zabbix agent checks on the host.

      here are the last 3 lines before the agent crashes.

      The Zabbix Agent 2 service has the status stopped in Windows Services.
      There is a log in the event viewer Event 7034, Service Control Manager
      The Zabbix Agent 2 service terminated unexpectedly, it has done this 1 time(s).
