Is there any update on this instance. I have much the same experience with a standalone docker instance (commercial release 6.2.2). The host isn’t under much load. but the backend restarts for no obvious reason, and the web-gui is then inaccessible.
Then trying to curl the $SENSU_BACKEND_AGENT_PORT fails - as in connection refuse not just the usually web application warning.
Hey,
Full update on the underlying issue here:

It looks like the fix will be in 6.3.0 release due soon.
