----------------------------------
Summary: ServerRequestStreamObserver is not properly closed
Key: RATIS-1834
URL: https://issues.apache.org/jira/browse/RATIS-1834
Project: Ratis
Issue Type: Bug
Components: gRPC, snapshot
Affects Versions: 2.5.0
Reporter: Song Ziyang
ServerRequestStreamObserver is not properly closed.
After receiving the COMPLETE flag from the client side, it immediately closes
the stream and also sends a COMPLETE flag to the client. see [1]. However, the
server observer may not finish processing requests in onNext, therefore, the
replies of these unfinished requests are lost.
If the client side waits on receiving all replies[2], this situation will
become a deadlock.
