Thanks Tom, you were in fact correct.

The client tripped over itself and forgot to finish reading some bytes when
reading a binary Text field. How that ended up looking like a NoData
message is beyond me but I have an extra check in place now that ensures
all types read all the bytes received for it. So another potential source
of errors fixed.

Thanks again,
