[erlang-bugs] beam.smp hangs and use 100% of cpu

[Lenrel Lenrel]

I have compiled  from source erlang 17.3 and rabbitmq 3.3.5.

Then I generate a load of aprox. 200 msg/s to rabbitmq exchange.

After a couple of minutes, process beam.smp hangs and use 100% of cpu.

The rabbitmq stops receiving connections and can't do anything with
rabbitmqctl.


The same thing happens when I compile older versions of erlang and rabbitmq
(R16B03 / 3.1.5).



This is the strafe -f -p:
