[sergey-safarov]

I automating rabbitmq initialization in cloud installation.
And found error

[root@rmq-a-1 ~]# rabbitmqctl await_startup
warning: the VM is running with native name encoding of latin1 which may cause Elixir to malfunction as it expects utf8. Please ensure your locale is set to UTF-8 (which can be verified by running "locale" in your shell)
Error:
{:badarith, [{:erlang, :div, [:infinity, 100], []}, {:rabbit, :wait_for_boot_to_start, 2, [file: 'src/rabbit.erl', line: 769]}, {:rabbit, :await_startup, 3, [file: 'src/rabbit.erl', line: 760]}, {:rpc, :"-handle_call_call/6-fun-0-", 5, [file: 'rpc.erl', line: 197]}]}

Thanks for using RabbitMQ and for reporting this issue. It has already been fixed in #2144

Thanks for letting us know what version you're using. Yes, I can reproduce this issue using the steps you provide.

Once this change makes it through the pipeline we will produce a 3.8.2 preview for you to use in your automation work.

[sergey-safarov]

Where i can download preview rpm build?
Thanks

[michaelklishin]

We will post a link here once Concourse produces a new alpha (development) build.

[michaelklishin]

I posted an alpha that did not contain this commit, we have to wait a bit more.

[michaelklishin]

3.7.22-alpha.5 contains this PR. Thanks again.

Hi, this is just a workaround script for people like me that cannot upgrade Rabbitmq immediately (but in the future yes):

            rabbitmq_await() {
              # Workaround of https://github.com/rabbitmq/rabbitmq-server/issues/2158
              # TODO: remove this sleep if rabbitmq >= 3.8.2.
              while ! rabbitmqctl cluster_status &>/dev/null ; do
                sleep 2
              done
              echo "Rabbitmq ready!"
            }
