Symptoms

A stream FIN is never sent and the connection times out.

Impact

Instead of closing when a request is complete, QUIC connections may hang around for the duration of the idle timeout.

Conditions

QUIC has a bidirectional stream waiting to send a FIN when it receives an ACK for the last of the data sent on that stream.

Workaround

None.

Fix Information

QUIC now sends a stream FIN when needed.
