The server sends data to the client and loses the packet

[skystar66]

I have a question. I have a scenario where after the client and the server establish a long connection through quic, the server automatically creates N QuicStreamChannels with the client and simulates sending 10,000 messages to the client through QuicStreamChannel. However, the data volume of the package received by the client is incomplete. Sometimes it receives more than 2,000 messages, and sometimes it receives more than 7,000 messages. Packet loss occurs. Can you help me analyze what caused the problem?

The server error message is as follows
