Root Cause

The gRPC message was corrupted during transmission, causing checksum verification to fail.

generic

中文

gRPC 消息在传输过程中损坏，导致校验和验证失败。

Workarounds

  1. 95% success 
    creds := credentials.NewClientTLSFromCert(certPool, ""); conn, err := grpc.Dial(address, grpc.WithTransportCredentials(creds))
  2. 90% success 
    req := &pb.Request{Data: data, Checksum: sha256.Sum256(data)}; server verifies checksum
  3. 85% success 
    backoff := grpc.Backoff{MaxDelay: 5 * time.Second}; conn, err := grpc.Dial(address, grpc.WithConnectParams(grpc.ConnectParams{Backoff: backoff}))

Dead Ends

Common approaches that don't work:

  1. Retrying the same request without checks. 70% fail

    Corruption may be transient but same data may fail again.

  2. Turning off checksum checking. 80% fail

    Data integrity risk.

  3. Blaming server for incorrect checksum. 50% fail

    Network issues are common cause.
