What will happen if the rabbitmq crashes, will nameko reconnect after rabbitmq comes up?.
we are seeing that with only 4-5 services and low load i.e. 4 msg/sec , rabbitmq inside a docker , is crashing and when rabbitmq crashes, all services stops or get hung
i.e. we are seeing behavior similar to this https://groups.google.com/forum/?nomobile=true#!msg/nameko-dev/POBxAV71TUE/XRqyV-iHCwAJ

Yes. As long as the process stays up, the consumers should attempt to reconnect.

Hanging and crashing would mean very different causes. If you see the process terminate with a crash, you may be experiencing the above. It very specifically happens when an exception occurs inside get_dependency. This is a “feature” that we could easily remove, and is also easily worked-around by running Nameko under a process manager like supervisord.
Please post a stacktrace or otherwise describe the “hang” in more detail.
