[rabbitmq-discuss] Rabbitmq 3.2.4 running out of memory

[srikanth tns]

Hi ,

Thanks for suggesting the changes.
we have applied the relevant changes to config file for statistics and RAM
upgrade. Things seem to be stable now but we will monitor the usage to see
if it jumps off again.
here is a screenshot of how its looking now. Please let me know if this is
promising , also is there any possibility of memory leaks and how we can
avoid them?
