Hello Victor,
think i found something. System must be a VMWare Windows VM (Server 2008R1/2016), VMWare tools installed. Steps to reproduce:
- NetXMS Agent is running and still the nxagentd.exe handle from svchost.exe exist
- Stopping VMWare Tools Service (Service "VMTools", V10.1.15)
- Waiting for couple of minutes (1-3)
- nxagentd.exe handle from svchost.exe is gone away
Now, i can update des NetXMS Agent via NetXMS Server or agent installer exe
I can this reproduce on all our Windows VM's (Server 2008R2/2016 64bit).
Physical machines seems not be affected. Here i can upgrade the agent without any problems (i looked at process explorer bevor update: there exist no nxagentd.exe handle from svchost.exe
Hope this helps and perhaps, you can find a workaround/fix for that...
Greetings
Marco
