Maxim Rydkin edited comment on QPID-2410 at 2/19/16 3:15 AM: ------------------------------------------------------------- So framing errors I'm seeing seem to be due to the fact that the SslIoBuff returns a buffer of size (base->byteCount - sizes.cbHeader - sizes.cbTrailer) which is too small to hold a full frame of data if the message gets split into multiple frames. Then the TCPConnector::encode gets invoked in a loop forever, writing no data, because the frame doesn't fit into a buffer. It seems happier if I make them pluses so its big enough to hold header, data, and trailer - but then connection gets dropped anyway. Maybe because the new buffer exceeds agreed upon max-frame-size was (Author: maxrydkin): So framing errors I'm seeing seem to be due to the fact that the SslIoBuff returns a buffer of size (base->byteCount - sizes.cbHeader - sizes.cbTrailer) which is too small to hold a full frame of data if the message gets split into multiple frames.
