Hi,
I did some additional tests. Over all I think it has something to do with plugin-handling.
Before that I have removed the complete old CheckMK Stuff from servers.
Reproduceable behaviour:
- Baked agent installed
- Service is running. check_mk_agent.exe and cmk-agent-ctl.exe are show in process explorer
- port 6556 is NOT bound to any process
- Service stopped
- complete content of %programdata%\checkmk\agent\plugins delete
- Service startet
- port 6556 is bound to process cmk-agent-ctl.exe
