[rabbitmq-discuss] How to debug queue memory leak

[Max Kuznecov]

Here's again my data:

rabbitmqctl report: http://pastebin.com/Qj5m2kjY

rabbitmqctl eval

rabbitmqctl eval
'sys:get_status(rabbit_misc:string_to_pid("<rabbit at sps.3.3412.3>")).
output is huge - 15 megabyte!
I've compressed it - http://dl.dropbox.com/u/22762166/report2.bz2

P.S. I'm posting the messages to the list as well, but then I get auto
reply - "message is pending for approval" or something like that.
