Ah, I completely forgot that 'report' reports on all nodes. Sorry.

There are about 1100 connections and 8400 channels. Are those the
numbers you expect to see?

How big are the messages?

Please run the following on crl0015 when it is using lots of memory:

rabbitmqctl eval 'begin {L, Pid} =
lists:last(lists:sort([{length(element(2, process_info(P, binary))), P}
|| P <- processes()])), {L, Pid, process_info(Pid)} end.'

(all on one line) and post the output.

Regards,

Matthias.
