Hi Paul,

Thanks for the detailed diagnostics.

Can you supply the output of etop? e.g.
 etop -node rabbit at rabbit-node-name -lines 100 -sort reductions

If you can get the output of "rabbitmqctl report" that will also be useful.

Is there anything noteworthy in the broker or system logfiles?

Can you tell what system calls are being executed by the threads with
high load? e.g. "strace -pid 6017"

Were any changes made to the sources?
