Description of problem

In the client , the trace is:
TRACE write message: GenMessage { header: MessageHeader { length: 99, stream_id: 1, type_: 1, flags: 0 }, payload: [10, 18, 109, 111, 100, 101, 108, 46, 77, 111, 100, 101, 108, 83, 101, 114, 118, 105, 99, 101, 18, 8, 84, 101, 120, 116, 67, 104, 97, 116, 26, 3, 10, 1, 49, 32, 128, 168, 214, 185, 7, 42, 18, 10, 5, 107, 101, 121, 45, 49, 18, 9, 118, 97, 108, 117, 101, 45, 49, 45, 49, 42, 18, 10, 5, 107, 101, 121, 45, 49, 18, 9, 118, 97, 108, 117, 101, 45, 49, 45, 50, 42, 16, 10, 5, 107, 101, 121, 45, 50, 18, 7, 118, 97, 108, 117, 101, 45, 50] }

In the server, the trace is:

[00:06:49.978] (1531bb179700) TRACE Reader task exit.
[00:06:49.978] (1531bb179700) TRACE Writer task exit

Looks like the client send the conn is closed . Occasionally, successful data transmission occurs after extensive attempts.

Expected result

I don't know what will cause this problem . Need help.

Actual result

I write it in a deamon test demon
