Receiver (Consumer) does not receive message that are larger than ~4.15kb about rhea HOT 3 OPEN

Rhea certainly handles messages much larger than that and no special configuration should be necessary. I don;t know what UMB is though.

I would get a protocol trace either client or broker side (or using wireshark) and see what that shows. (For rhea you can get a trace by setting env var DEBUG=rhea*)

When I had debug enabled for rhea, I didn't see any indication that the app ever received the larger message. What really strange about this issue is that the broker believes it delivered the message and the consumer and will reduce our credit window.

I'm very confused because as of right now it looks like our messages ( that are larger than ~4.15kb) are in limbo... outside of our consumer but not within the broker itself. Nothing from our consumer side indicates that we received the message and everything from the brokers perspective makes it seem like the message was delivered.

I'll keep debugging and try different things.

Can you get a broker side protocol trace? Env var PN_TRACE_FRM=1 should do it if I recall correctly.
