[rabbitmq-discuss] flow control in rabbitmq

[sandeep kumar]

Hi ,

I have used single rabbitmq node , And I set  memory_high_watermark to a
small value(0.05)
and messages are being sent to the rabbitmq node at a higher rate.
When memory is about to be breached because of higher rate of messages to
the node creation of .rdq files is observed.
when the memory consumtion crosses the limit all connections to the node
getting blocked is observed.
At this point of time there is neither increase in queue size nor .rdq
size, but publish to queue statemt is getting executed.

Questions are :

where are the published messages are getting store when connections to
queue are in blocked state

how to handle this kind of scenario gracefully
