Cloud Run autoscaling behaviour

Why would a CR instance scale to a large number (not very large though)  with low CPU and memory utilization (both < 50%). The only reason I can think off is container crashes any other reason?

typically, container crashes or something in error reporting where dependencies are not met, I would look in the log and isolate on a single container for the error, if a sidecar is involved as a backend and it is not available - add a health or liveliness probe to ensure service is up, likewise if you're using EFS or DB on the backend verify the services are up and ensure there isn't an error

Thanks @djs_75  There is no sidecar involved. Thanks for your suggestion on adding health checks to the CR service.
