Thanks Adam, I had further investigation, the original post of error was not correct, it was not the problems of length, the file length was correct, but the file was corrupted, there were some junk characters like "^@^@^@^L^B^@^B^P^D^H<80><9b>^F^P]^X<80><9b>^F" inserted to the middle of protobuf bytes / string and chopped off the connect string after serialisation. I don't think there are any issues of coding and serialisation / deserialisation in general, I have used the same code for years without any issues until when the files increased to 17 KB, it corrupted.
