Masstransit 3.5.7 causes leak in erlang processes & number of channels

[Guy Kolbis]

Hi

we are using 

masstransit 3.5.7

rabbitmq 3.6.5

Our environment is running ~2000 microservices.

We use cluster.

We are experiencing a leak in the number of channels as well as the number of erlang processes being used.

In the image below you can see that we have ~46,000 channels.

If we look into the connections, we see there are many idle channels in each connection.

In addition, maybe related to it, we can see that the number of erlang processes is constantly increasing.

Can someone please share some information and assist with this behavior?
