[rabbitmq-discuss] Rabbitmq 2.7.1 / R14B02 crash - updates

Fri Mar 23 12:09:12 GMT 2012

Hello ,

I executed these comands on the server:
# ps aux | grep beam >  memory.txt
# rabbitmqctl status >> memory.txt

and attacheed the file.

The memory used by the queues:
root at rabbitmq-01:/var/lib/rabbitmq/mnesia/rabbit at rabbitmq-01/msg_store_persistent#
rabbitmqctl list_queues  memory | awk '{ sum+=$1} END {print sum}'
324448024.

Why the beam process takes 1.4 Gb and the rabbitmqctl status reports
only a few hundred Mb?
I see the same value(raported by rabbitmqctl status) in the management
web inteface. 
Is there a way to find where goes the memory?
Am I using a wrong erlang version?

Thank you,
 Andrei
