yes RSMB does have that behaviour - the read buffer is increased
to the size needed to read in that message, but never reduced.
You could raise an issue if it's something you'd like fixed.
I assume that you are using RSMB for MQTT-SN? We have a newly
contributed MQTT-SN gateway which is currently undergoing
testing. Perhaps that would be a good replacement?

RSMB lead to be small broker but I have use RSMB to publish
a "big" binary message (100MB) and the memory increases when
the message was sent and no longer descends. Looks like the
memory allocated for the message transfer was not as
deallocated. The behavior is not cumulative: if published
after the big message any other smaller message, memory size
does not change but if we try to publish bigger one, the
memory increases and do not fall. RSMB keeps memory allocated
equal to the size of the largest forwarded message.
Is this normal ? (Mosquitto don't have this strange
