Saw some errors with Cerbos today triggered by a ~moderate amount of volume. We're using grpc + a load balancer and started seeing a lot of connection refused errors similar to what is described here: https://github.com/grpc/grpc-node/issues/1969 Curious if you've seen this before?

No we haven't seen that before. I wonder whether there's a mismatch between how long the LB keeps a connection open vs the default max connection age set by Cerbos (10 minutes). Try reducing the LB keep-alive idle timeout to less than 10 minutes or alternatively, increasing the Cerbos timeout (server.advanced.grpc.maxConnectionAge: https://docs.cerbos.dev/cerbos/latest/configuration/index.html#_full_configuration)
