[rabbitmq-discuss] Memory not flushing?

[Jason McIntosh]

Running 3.3.4, we have a situation (maybe an erlang R14B04 issue?) where
rabbit hits the memory alarm and never goes out of it.  The queue (with
over 100 million messages in it) is showing 0 memory usage, all messages
paged to disk, 0 in ram.  Disk IO is non existent.  Just looking for any
ideas/suggestions?  I saw this message:
http://lists.rabbitmq.com/pipermail/rabbitmq-discuss/2013-April/026649.html
But wasn't sure it applied since the ram counts are 0?  If that's still
probably the issue, is there a way to set the target ram count to something
other than infinity?  e.g. rabbitmqctl set_paramter myqueue
target_ram_count 0.50?  Below are the memory reports from a few place.
Thanks!
Jason
