Yes and I replied to the ticket. The base64encoded data received is the same as that which was sent, so I do not think data length is the issue. Also if I send the file data just by itself without putting it into an array, the file arrives at the server intact and can be base64Decoded and decrypted and saved to disk with no issues. Further if I run the server on a MacOS device it works fine.
I think that read from socket with messages will continue to read until it encounters an EOF, and THEN it will generate the message. It would be a pretty poor implementation to send the message in the middle of receiving data! The issue is that the arrayDecode on Windows is not producing the same result as arrayDecode on MacOS. I really think that Monte was on to it with the way that arrayDecode handles binary data. Anyway as I mentioned in the bug report, I will probably send the files separately from the array to break up the payload.
