** Description changed:
+ Ubuntu: disco development
+
On a new deployment, erlang will create a cookie with a random secret
value for use; however it must have 0400 permissions otherwise erlang
will refuse to use it.
On s390x the automatic cookie creation code fails with:
- args: []
- format: "Failed to change mode: einval"
- label: {error_logger,error_msg}
+ args: []
+ format: "Failed to change mode: einval"
+ label: {error_logger,error_msg}

Crash dump is being written to: /var/log/rabbitmq/erl_crash.dump...done
Works fine on all other architectures so suspect something endian
related.
