Please check gRPC doc to understand this. Usually, this means network broken to OAP

I searched for documents about grpc in SkyWalking documents, but it didn't help me.
It can report and collect logs of application startup and application running, but when I stop the application, a shutdown event cannot be reported. What happened?
Can you give a link to the documentation about grpc? thank you

Not the doc of SkyWalking. This error is from gRPC lib.

but when I stop the application, a shutdown event cannot be reported

I think this could be caused by kill -9 rather than gracefully shutting down. The shutdown even reports through JVM shutdown hook, so, don't terminate the process.

This issue has been resolved. How was it resolved? I encountered the same problem

When I gracefully shut down the service, the service shutdown event cannot be reported, and the agent-api logs show this error. My OAP services are all on the local machine, and in the SkyWalking UI event list, there is only the start event, not the stop event. What could be the reason for this?
