Hello, we are currently on ACS 4.20, but i had this effect with previous versions as well. After a few days, the cloudstack agent becomes unresponsive. It still shows up as healthy in ACS, the agents logs look perfectly normal. But it does not execute anything anymore. After restarting the agent it magically starts working again.
I am bit lost in debugging this, maybe someone has a hint where to start? Currently its „hotfixed“ with a nightly restart of the agent. Cheers, Juergen
