Steps to reproduce this issue

Use triple call provider api with istio sidecar injection, after about 1-2 hours, get RPC error, the log shows no provider problem.

By troubleshooting, we found the problem may be netty get the wrong connection status, the connection is health, but netty mark it as bad, so the RPC has been terminated.

What's the service discovery mechanism that is used on the consumer side?

Is dubbo consumer SDK or sidecar responsible for subscribing addresses from registry?
